Point-of-Need DNA Testing for Detection of Foodborne Pathogenic Bacteria

Foodborne pathogenic bacteria present a crucial food safety issue. Conventional diagnostic methods are time-consuming and can be only performed on previously produced food. The advancing field of point-of-need diagnostic devices integrating molecular methods, biosensors, microfluidics, and nanomaterials offers new avenues for swift, low-cost detection of pathogens with high sensitivity and specificity. These analyses and screening of food items can be performed during all phases of production. This review presents major developments achieved in recent years in point-of-need diagnostics in land-based sector and sheds light on current challenges in achieving wider acceptance of portable devices in the food industry. Particular emphasis is placed on methods for testing nucleic acids, protocols for portable nucleic acid extraction and amplification, as well as on the means for low-cost detection and read-out signal amplification

Luminescent Metal-Organic Frameworks for Electrochemiluminescent Detection of Water Pollutants

Modern lifestyle has increased our utilization of pollutants such as heavy metals, aromatic 17 compounds, and contaminants of rising concern involving pharmaceutical and personal products 18 and other materials that may have an important environmental impact. Especially, the ultimate re-19 sults of intense use of highly stable materials, such as heavy metals and chemical restudies are that 20 they turn into waste materials which, when discharged, accumulate in the environment water bod-21 ies. In this context, the present review presents application of metal-organic frameworks (MOFs) in 22 electrochemiluminescent (ECL) sensing for water pollutant detection. MOF composites applied as 23 innovative luminophore or luminophore carriers, materials for electrode modification and enhance-24 ment of co-reaction in ECL sensors have enabled sensitive monitoring of some most common con-25 taminants of emerging concern such as heavy metals, volatile organic compounds, pharmaceuticals, 26 industrial chemicals and cyanotoxins. Moreover, we provide future trends and prospects associated 27 with ECL MOF-composites for environmental sensing

Drawing as a beginning: Case report

Treatment of patients with affective disorders during hospitalisation at the Institute of Mental Health includes pharmacotherapy, individual supportive therapy, group and expressive therapies including art therapy. Art therapy takes a place weekly, it lasts one hour during which patients paint for twenty minutes and then discuss their paintings in the group for the next forty minutes. In this paper the case of a patient who has been treated as recurrent depressive disorder (F33) and mixed personality disorder (F61) is presented. During previous years of treatment the patient had no inability to verbalise his symptoms and feelings, which led to difficult understanding of his actual psychopathology. After applied integrative treatment, pharmaco – and psychotherapy including expressive – art therapy, with the help of the supportive group, the patient for the first time since the beginning of the treatment spoke about his thoughts and feelings of hopelessness, sorrow, alienation and loneliness. All of the applied psychometric scales have shown improvement, for depression – MADRS, for anxiety – VAS and for functionality – SDS. This clinical example shows how the art therapy and interreaction with the group, which was supportive and highly associative, can turn the non-verbal into verbal and non-communication into communication

Direct glyphosate soil monitoring at the triazine-based covalent organic framework with the theoretical study of sensing principle

Covalent organic frameworks (COFs) are emerging as promising sensing materials due to their controllable structure and function properties, as well as excellent physicochemical characteristics. Here, specific interactions between a triazine-based COF and a mass-used herbicide – glyphosate (GLY) have been utilized to design a disposable sensing platform for GLY detection. This herbicide has been extensively used for decades, however, its harmful environmental impact and toxicity to humans have been recently proven, conditioning the necessity for the strict control and monitoring of its use and its presence in soil, water, and food. Glyphosate is an organophosphorus compound, and its detection in complex matrices usually requires laborious pretreatment. Here, we developed a direct, miniaturized, robust, and green approach for disposable electrochemical sensing of glyphosate, utilizing COF’s ability to selectively capture and concentrate negatively charged glyphosate molecules inside its nanopores. This process generates the concentration gradient of GLY, accelerating its diffusion towards the electrode surface. Simultaneously, specific COF-glyphosate binding catalyses the oxidative cleavage of the C–P bond and, together with pore nanoconfinement, enables sensitive glyphosate detection. Detailed sensing principles and selectiveness were scrutinized using DFT-based modelling. The proposed electrochemical method has a linear working range from 0.1 μM to 10 μM, a low limit of detection of 96 nM, and a limit of quantification of 320 nM. The elaborated sensing approach is viable for use in real sample matrices and tested for GLY determination in soil and water samples, without pretreatment, preparation, or purification. The results showed the practical usefulness of the sensor in the real sample analysis and suggested its suitability for possible out-oflaboratory sensing

Electrochemical biosensor based on NAD(P)H-dependent quinone reductase for rapid and efficient detection of vitamin K3

Vitamin K refers to a group of vitamins that play an important role in blood coagulation and regulation of bone and vascular metabolism. However, vitamin K3 may give severe side effects in animal and humans when improperly added to food and feed due to its toxicity. Here, an electrochemical biosensor, based on the YaiB NADPH-dependent quinone reductase from Lactococcus lactis (YaiB), was developed to achieve rapid and redox probe-free detection of vitamin K3. First, the ability of the carbon electrode to distinguish between 1,4-benzoquinone and hydroquinone was demonstrated. Then, we engineered YaiB to work as a bioreceptor immobilized at the electrode and its sensitivity and specificity to reduce vitamin K3 were demonstrated. Finally, to demonstrate the practical potential of the biosensor, we tested it directly in spiked milk samples, achieving 15-minute quantification of the vitamin K3. The limit of detection was 0.87 µM and 4.1 µM in buffer and milk, respectively

Antioxidant and cell-friendly Fe2TiO5 nanoparticles for food packaging application

An emerging technology of active packaging enables prolongation of food shelf life by limiting the oxygen transfer and the reactivity of free radicals, which both destruct food freshness. In this work, Fe2TiO5 nanoparticles were synthesized using a modified sol–gel method and evaluated as an enforcement of alginate food packaging film. Pure phase Fe2TiO5 nanoparticles had an average particle size of 44 nm and rhombohedral morphology. Fe2TiO5 nanoparticles induce no cell damage of human Caco-2 epithelial cells and show no inhibitory effect towards growth of a panel of bacterial strains, suggesting good biocompatibility. Films obtained by incorporation of Fe2TiO5 nanoparticles into alginate using the solvent casting method show no migration of iron or titanium ions from films to food simulants again suggesting their safety as a packaging material. Fe2TiO5 nanoparticles also showed strong antioxidant efficiency as determined using the DPPḢ assay, and confirmed further in a preservation test on fresh fruit
