Drug testing complementary metal-oxide-semiconductor chip reveals drug modulation of transmitter release for potential therapeutic applications.

ABSTRACT: Neurodegenerative diseases, such as Parkinson's disease, Alzheimer's disease, and Huntington's disease, are considered incurable and significantly reduce the quality of life of the patients. A variety of drugs that modulate neurotransmitter levels have been used for the treatment of the neurodegenerative diseases but with limited efficacy. In this work, an amperometric complementary metal-oxide-semiconductor (CMOS) chip is used for high-throughput drug testing with respect to the modulation of transmitter release from single vesicles using chromaffin cells prepared from bovine adrenal glands as a model system. Single chromaffin cell amperometry was performed with high efficiency on the surface-modified CMOS chip and follow-up whole-cell patch-clamp experiments were performed to determine t
