Request InfoMY Polymers Ltd.BIO-133 Line Polymers from MY Polymers Ltd. combine a low refractive index of 1.33 and 1.34, minimal cytotoxicity, and minimal fluorescence. The low index matches the index of water and cells, enabling construction of 3D structures that do not degrade image quality in microscopy imaging. Examples include the construction of micro-chambers for live-cell imaging or micro-pillars to measure forces between cells. The polymers were specifically designed for the lowest possible cytotoxicity for the growth of cells. The BIO-133 polymers were also designed for minimal fluorescence, to allow...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2022 IssueSlow-Axis CollimatorThe Blue Meniscus Slow Axis Collimator (SAC) from Focuslight Technologies Inc. features an effective focal length of 9.7 mm with a concave-convex, acylindrical lens design for the collimation of the...Photonics.com 3/25/2024Wafer Inspection SystemThe LS9300AD from Hitachi is a system for inspecting the front and backside of non-patterned wafer surfaces for particles and defects.
