Desarrollo de un prototipo de biosensor basado en nanoconjugados de nanopartículas de carbono y papaína para la detección de cistatina c (cYS c) por Cavazos Jaramillo, Azael Adrián

“…Five known Cys C concentrations in a range of 0.9 to 3.0 µg/mL were used to establish a biosensor calibration curve, measuring the interaction between nanoconjugates and papain by cyclic voltammetry obtaining current values ranging from 61.77 to 51.11 µA. After obtaining the Cys C calibration curve, three serum samples from donors without a history of diagnosed renal damage were used to challenge the system, being possible to locate the I values in the calibration curve where the I values ranged from 52.57 to 74.88, 45.50 to 75.31 and 42.48 to 79.17 µA respectively. …”
