Functionalized carbon microarrays platform for high sensitive detection of HIV-Tat peptide

摘要

The detection of HIV disease at an early stage has significant clinical implications. We report the detection of HIV-TAT peptide on a functionalized three-dimensional carbon micropillar array platform. The sensor showed a linear relationship between HIV-TAT concentration and fluorescence intensity in the sub-nanomolar range with a detection limit of 50 pmol.
