Highly reproducible single-molecule analysis of transient structures of native proteins using m-Trap^® dual optical tweezers combined with Raman spectroscopy

A recent publication by Dai et al. in Nature Communications presents an optical tweezers-coupled Raman spectroscopy platform providing tuneable and reproducible surface-enhanced Raman spectroscopy (SERS) measurements. By combining a Raman microscope with the dual-trap optical tweezers and microfluidic flow chamber of the m-Trap®, the scientists were able to characterize three…

Early activation of single macrophages captured by the C-Trap^®

In a recent article published in Small Methods, researchers reveal a method that uniquely captures the early phase of oxidative stress response in macrophages. Employing the powerful combination of optical tweezers, confocal fluorescent microscopy, and microfluidics of the C-Trap®, they measured the real-time intracellular response of individual macrophages to a…
