JMAR Technologies

JMAR Technologies was a technology firm that developed advanced laser-based systems for microelectronics and life science applications. The company's most notable contribution to the healthcare sector was the BioSentry system, a laser-based sensor used for the real-time detection of waterborne pathogens such as Cryptosporidium and Giardia. This technology utilized multi-angle light scattering to provide continuous monitoring of water quality without the use of chemical reagents. Beyond water safety, JMAR provided laser-produced plasma (LPP) sources for X-ray lithography and microscopy. The company was publicly traded on NASDAQ but faced financial difficulties, leading to a Chapter 11 bankruptcy filing and the sale of its assets in 2009. The BioSentry technology was eventually acquired by ZMicro.
