Request Infoibidi GmbHIntegrated BioDiagnostics (ibidi) GmbH has unveiled the chemotaxis slide, a member of its μSlide series of flow-through devices for functional analysis of living cells. The slide enables motion tracking of slow-migrating cells such as chemotactic cancer cells in gradients and allows the formation of stable gradients for 48 h, permitting users to follow cells that move about one cell length per hour. Such gradient assays can be performed with low volumes, 3 μl for the cells and 18 μl for the chemokines. The slide comes with a software plug-in for Image J.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 5/17/2022Biomolecular Characterization DeviceThe Apollo biomolecular characterization device from RedShift BioAnalytics Inc. uses microfluidic modulation spectroscopy (MMS) technology to provide sensitive, precise measurements of biomolecule...Photonics Spectra February 2024 IssueAnalog Front End SensorThe AS7058 from ams OSRAM is an analog front end (AFE) that uses photoplethysmography (PPG) signals to improve the reliability and accuracy of wearable devices.
