By: A. De Alwis n, J. Denison n, R. Shah  n, G. McCarty n  & L. Sombers n 

author keywords: voltammetry; amperometry; chromaffincell; diffusion; catecholamine; dense corevesicle; carbon fiber microelectrode
TL;DR: This work demonstrates how electrode geometry can be exploited for improved detection of exocytosis events by addressing diffusional loss─an often-overlooked source of inaccuracy in single-cell measurements. (via Semantic Scholar)

2023 journal article

Untapped Potential: Real-Time Measurements of Opioid Exocytosis at Single Cells

JOURNAL OF THE AMERICAN CHEMICAL SOCIETY, 145(44), 24071–24080.

By: J. Denison n, A. De Alwis n, R. Shah  n, G. Mccarty n  & L. Sombers n 

TL;DR: Comparing the results collected at the two potentials reveals unique kinetics for these two neurochemical classes at the single-vesicle level, providing unprecedented insight into key differences between catecholamine and opioid neuropeptide release from isolated chromaffin cells.
