Title: Electrochemical and label-free immunosensors applied to point-of-care testings
Biography: Dr.Rosa F Dutra
Point-of-care testings hold great promise for economic, rapid and practical diagnosis of several diseases, benefiting those with high morbimortality rates. Electrochemical biosensors using amperometric transduction have several advantages as compared to optical and acoustical transductions due to their ease scale up, fast response and low cost connection with compact (hand-held) analyzers. However, several drawbacks on performance have limited their large use in clinical diagnostic. The purpose of this study is to describe some strategies of sensor platforms using conducting polymer integrating carbon allotropes including carbon nanotubes, graphene and fullerene, in order to overcome challenges required as a low limit of detection and a good reproducibility.
