Picoyune is a portable sensors company based in Berkeley, California. Founded in 2013 by Jay James PhD and Jeffrey Crosby PhD, Picoyune aims to improve environmental outcomes of impactful industrial processes by providing reliable, portable, and easy-to-use devices. Their next generation mercury monitors are revolutionizing the field of mercury analysis.

Using gold nanoparticles, Picoyune's technology utilizes a phenomenon called localized surface plasmon resonance (LSPR) for mercury analysis. When exposed to mercury vapor, the gold nanoparticles undergo a blue shift in their absorption peak. Unlike other vapor species, mercury can directly contribute to the LSPR of the gold/amalgam particles, resulting in high sensitivity for detecting mercury.

This selective adsorption improves the sensitivity, selectivity, and stability of plasmonic mercury sensing. Picoyune's innovative sensors have received grants from reputable institutions such as the NIH, NSF, ConservationXLabs, and DOE, further validating their commitment to advancing environmental research.
