    Get PDF
    In the era that we seek personalization in material things, it is becoming increasingly clear that the individualized management of medicine and nutrition plays a key role in life expectancy and quality of life, allowing participation to some extent in our welfare and the use of societal resources in a rationale and equitable way. The implementation of precision medicine and nutrition are highly complex challenges which depend on the development of new technologies able to meet important requirements in terms of cost, simplicity, and versatility, and to determine both individually and simultaneously, almost in real time and with the required sensitivity and reliability, molecular markers of different omics levels in biofluids extracted, secreted (either naturally or stimulated), or circulating in the body. Relying on representative and pioneering examples, this review article critically discusses recent advances driving the position of electrochemical bioplatforms as one of the winning horses for the implementation of suitable tools for advanced diagnostics, therapy, and precision nutrition. In addition to a critical overview of the state of the art, including groundbreaking applications and challenges ahead, the article concludes with a personal vision of the imminent roadmap.The financial support of PID2019-103899RBI00 (Spanish Ministerio de Ciencia e Innovación), and PMP22/00084, PI17CIII/00045, PI20CIII/00019 and PI22/00727 (AES-ISCIII) cofounded with FEDER funds Research Projects and the TRANSNANOAVANSENS-CM Program from the Comunidad de Madrid (Grant S2018/NMT-4349) are gratefully acknowledged.

    Anti-double stranded DNA antibodies: Electrochemical isotyping in autoimmune and neurological diseases

    Get PDF
    This work reports the first amperometric biosensor for the simultaneous determination of the single or total content of the most relevant human immunoglobulin isotypes (hIgs) of anti-dsDNA antibodies, dsDNA-hIgG, dsDNA-hIgM, dsDNA-hIgA and dsDNA-three hIgs, which are considered relevant biomarkers in prevalent autoimmune diseases such as systemic lupus erythematosus (SLE) as well as of interest in neurodegenerative diseases such as Alzheimer’s disease (AD). The bioplatform involves the use of neutravidin-functionalized magnetic microparticles (NA-MBs) modified with a laboratory-prepared biotinylated human double-stranded DNA (b-dsDNA) for the efficient capture of specific autoantibodies that are enzymatically labeled with horseradish peroxidase (HRP) enzyme using specific secondary antibodies for each isotype or a mixture of secondary antibodies for the total content of the three isotypes. Transduction was performed by amperometry (− 0.20 V vs. the Ag pseudo-reference electrode) using the H2O2/hydroquinone (HQ) system after trapping the resulting magnetic bioconjugates on each of the four working electrodes of a disposable quadruple transduction platform (SP4CEs). The bioplatform demonstrated attractive operational characteristics for clinical application and was employed to determine the individual or total hIgs classes in serum from healthy individuals and from patients diagnosed with SLE and AD. The target concentrations in AD patients are provided for the first time in this work. In addition, the results for SLE patients and control individuals agree with those obtained by applying ELISA tests as well as with the clinical ranges reported by other authors, using individual detection methodologies restricted to centralized settings or clinical laboratories.Depto. de Química AnalíticaFac. de Ciencias QuímicasTRUESpanish Ministerio de Ciencia e InnovaciónAES-ISCIIIComunidad de Madridpu

    Direct PCR-free electrochemical biosensing of plant-food derived nucleic acids in genomic DNA extracts. Application to the determination of the key allergen Sola l 7 in tomato seeds

    Get PDF
    A novel and disposable electrochemical biosensor for PCR-free and selective detection of Sola l 7, a non-specific lipid transfer protein (nsLTP) found in tomato seeds associated to severe symptoms of tomato-allergic patients, is reported in this work. The methodology involves the formation of DNA/RNA heterohybrids by sandwich hybridization of a specific fragment of the Sola l 7 allergen coding sequence with appropriate RNA probes designed and described for the first time in this work. Labeling was carried out with commercial antibodies specific to the heteroduplexes and secondary antibodies conjugated with HRP onto the surface of magnetic beads. Amperometric transduction was performed upon magnetic capture of the resulting magnetic bioconjugates on screen-printed electrodes using the system H2O2/HQ. A comparison of the sandwich hybridization format with a direct approach as well as between different labeling strategies was performed. The LOD value achieved was 0.2 pM (5 amol in 25 μL). The biosensor was successfully applied to the selective analysis of the targeted Sola l 7 specific region directly in just 100 ng of non-fragmented denatured genomic DNA extracted from tomato seeds.The financial support of the Spanish Ministerio de Economía y Competitividad Research Projects, CTQ2015-64402-C2-1-R, SAF2017-86483-R and the TRANSNANOAVANSENS Program from the Comunidad de Madrid (Grant P2018/NMT-4349) are gratefully acknowledged.

    Use of autologous tooth-derived graft material in the post-extraction dental socket. Pilot study

    Get PDF
    The objectives of the present pilot study are to compare via CBCT the alveolar contraction suffered both vertically and horizontally between the control group and the group using autologous dental material (ADM), as well as to study the densitometric differences between both post-extraction sockets. A split-mouth study was performed in n = 9 patients who required two extraction of single-rooted teeth deemed suitable for deferred rehabilitation with osseointegrated implants. Two groups were formed ? a control group, in which the post-extraction socket was not filled, and an ADM group, in which the alveolar defect was filled with freshly processed autogenous dental material. Both dimensional and densitometric analyses of the alveoli were performed in both groups immediately after surgery (baseline), as well as 8 weeks and 16 weeks later. The mean height of alveolar bone loss was: VL (Control 1.77 mm, loss of 16.87% of initial alveolar height; ADM 0.42 mm, loss of 4.2% of initial alveolar height), HL-BCB (Control 2.22 mm, ADM 0.16 mm, p= 0.067 at 16 weeks). The mean bone loss of the vestibular width (VL-BCB) was much higher in the control group (1.91 mm at 1 mm, 1.3 mm at 3 mm, and 0.89 mm at 5 mm) than in the ADM group (0.46 mm at 1 mm, 0.21 mm at 3 mm, 0.01 at 5 mm, p=0.098 at 16 weeks). At 16 weeks, densitometric analysis of the coronal alveolar area revealed a bone density of 564.35 ± 288.73 HU in the control group and 922.68 ± 250.82 HU in the ADM group (p=0.045 ). In light of these preliminary results, autologous dentine may be considered a promising material for use in socket preservation techniques

    Tackling CD147 exosome-based cell-cell signaling by electrochemical biosensing for early colorectal cancer detection

    Get PDF
    The great opportunities represented by exosomes in liquid biopsy diagnostics and the relevance of CD147 protein as diagnostic and prognostic cancer biomarker led us to develop the first bio-electroanalytical platform for the determination of exosomal CD147 (exoCD147) by exploiting micro-sized magnetic beads coated with specific anti-CD147 antibodies. The captured exosomal target protein was sandwiched by specific biotin functionalized detector antibodies followed by attaching streptavidin-HRP conjugate to perform the amperometric reading using screen-printed carbon electrodes (SPCEs) as electrode transducers in the presence of hydroquinone (HQ) and H2O2. The analytical and operational characteristics achieved by implementing this simple methodology allowed the sensitive (LOD 29 pg mL-1) and selective determination of CD147 and the analysis of exoCD147 in different but inter-related real clinical scenarios including lysed and entire exosomes previously isolated from CRC cell lines with different metastatic potential. The obtained results, in agreement with those provided by ELISA and WB, proved the reliability of the developed immunosensor and its potential to isolate or identify specific subpopulations of exosomes based on the differential expression of characteristic surface biomarkers.The financial support of PID2019-103899RB-I00 (Spanish Ministerio de Ciencia e Innovación) Research Project and the TRANSNANOAVANSENS-CM Program from the Comunidad de Madrid (Grant S2018/NMT-4349) are gratefully acknowledged.

    Dextran-coated nanoparticles as immunosensing platforms: Consideration of polyaldehyde density, nanoparticle size and functionality

    Get PDF
    Magnetic nanoparticles (MNPs) can be used as antibody carriers in a wide range of immunosensing applications. The conjugation chemistry for preparing antibody-MNP bionanohybrids should assure the nanoparticle’s colloidal dispersity, directional conformation and high biofunctionality retention of attached antibodies. In this work, peroxidase (HRP) was selected as model target analyte, and stable antibody-MNP conjugates were prepared using polyaldehyde-dextrans as multivalent linkers, also to prevent nanoparticles agglomeration and steric shielding of non-specific proteins. Under the manipulation of the oxidation variables, MNP-conjugated antibody showed the highest Fab accessibility, of 1.32 μmol analyte per μmol antibody, corresponding to 139 μmol aldehyde per gram of nanocarrier (5 mM NaIO4, 4 h). Demonstrating anti-interference advantage up to 10% serum, colorimetric immunoassay gave a detection limit (LOD) of 300 ng mL− 1 , while electrochemical transduction led to a considerable (680 times) improvement, with a LOD of 0.44 ng mL− 1 . In addition, polyaldehydedextran showed priority over polycarboxylated-dextran as the multivalent antibody crosslinker for MNPs in terms of sensitivity and LOD value, while immunosensors constructed with carboxylated magnetic microbeads (HOOC-MBs) outperformed MNPs-based immunoplatforms. This work sheds light on the importance of surface chemistry (type and density of functional groups) and the dimension (nanosize vs micrometer) of magnetic carriers to conjugate antibodies with better directional orientation and improve the analytical performance of the resulting immunosensors

    Angiogenesis inhibitor or aggressiveness marker? The function of endostatin in cancer through electrochemical biosensing

    Get PDF
    This work reports the first electrochemical bioplatform developed for the determination of human endostatin (HE), a biomarker with recognized antiangiogenic potential whose elevated circulating levels have also been associated with the development of aggressive cancers. The developed electroanalytical biotool combines the benefits of using magnetic microparticles for the implementation of sandwich immunoassays and amperometric transduction on disposable carbon electrodes. A limit of detection (LOD) of 34.1 pg mL-1 for HE standards and a selectivity suitable for its foray into the clinical oncology area, are demonstrated. The determination of HE in clinical samples such as lysates and secretomes of colorectal cancer (CRC) cells, plasma, and tissue samples from patients with CRC in different stages, has been faced with satisfactory results showing the ability for discriminating the metastatic capabilities of cells and for identifying and staging CRC patients. The developed bioplatform allows precise quantitative determinations, requiring minimal pre-treatments and sample amounts in only 75 min. In addition, due to the instrumentation and the type of substrates used in the detection step, the biotool is compatible with implementation in multiplexed and/or point-of-need devices, features in which this bioplatform is advantageous with respect to the enzyme linked immunosorbent assay (ELISA) or immunoblotting technologies.The financial support of PID2019-103899RB-I00 (Spanish Ministerio de Ciencia e Innovación) Research Project and PI20CIII/00019 Grant from the AES-ISCIII Program co-founded by FEDER funds and the TRANSNANOAVANSENS-CM Program from the Comunidad de Madrid (Grant S2018/NMT-4349) are gratefully acknowledged.
