Innovative sensors for age-related diseases

Point-of-care diagnosis is evolving together with the fast development in terms of detection and quantification ability of the sensing techniques. This chapter covers 5 different topics of innovative (bio)sensors that were designed with the aim of giving new insights to overcome many of the hurdles that still impair the widespread use of portable sensing technology. Novelty was achieved by applying inexpensive materials with tuned functions and refined recognition towards biomarkers of various age-related pathologies. Diverse strategies were followed in order to attain improved properties on relevant parameters of sensor performance such as selectivity, sensitivity, biocompatibility and autonomy. Thus, the foreseen biomedical applications are vast.The authors gratefully acknowledge the financial support from IBEROS project (Instituto de Bioingeniería en Red para el Envejecimiento Saludable, INTERREG POCTEP/0245_IBEROS_1_E) supported by FEDER, also within the cooperation region of Galicia/Spain and North of Portugal.
