Founded in 2011 based on the patented techniques developed by Dr. Ling Zang, Vaporsens develops a revolutionary sensor system capable of detecting a broad range of explosive vapors with unprecedented sensitivity and speed. The sensor 1) detects explosives that remain challenging for current detection technologies, 2) has high throughput providing results in seconds, 3) can be used in small, portable devices, and 4) provides "stand-off" or distance detection.

Founded in 2010 based on the patented technology developed by Dr. Ling Zang, Metallosensors focuses its business on research, development and manufacturing of highly efficient fluorescence sensor materials and devices for expedient detection of trace metal ions in aqueous systems, including mercury (Hg2+).

Metallosensors was recently awarded a SBIR grant from NSF for developing next generation of device for Trace Mercury Detection.

Super-fine Safety Nets


We have developed a new generation of extremely acute sensing devices using nanowires. Together, these infinitesimally small threads act as super-fine filters that can catch airborne molecules from explosives (such as TNT). This patented technique was licensed to FLIR, a leading manufacturer in trace detection of explosives.
