Low threshold T-type calcium current in rat embryonic chromaffin cells
(2001)
1. The gating kinetics and functions of low threshold T-type current in cultured chromaffin cells from rats of 19-20 days gestation (E19-E20) were studied using the patch clamp technique. Exocytosis induced by calcium ...
Imaging local electrochemical current via surface plasmon resonance
(American Association for the Advancement of Science, 2010-03)
We demonstrated an electrochemical microscopy technique based on the detection of variations in local electrochemical current from optical signals arising from surface plasmon resonance. It enables local electrochemical ...
Investigation of the interaction between Tc85-11 protein and antibody anti-T cruzi by AFM and amperometric measurements
(Elsevier B.V., 2006-07-15)
This present work reports on development of an amperometric immunosensor for the diagnosis of Chagas' disease using a specific glycoprotein of the trypomastigote surface, which belongs to the Tc85-11 protein family of ...
Immobilization of streptavidin in sol-gel films: Application on the diagnosis of hepatitis C virus
(Elsevier B.V., 2006-10-15)
Recent advances have accelerated the development of biosensors for the analysis of specific gene sequences. In this kind of biosensor, a DNA probe is immobilized on a transducer and the hybridization with the target DNA ...
