Droplet microreactor for high-throughput fluorescence-based measurements of single catalyst particle acidity

Microsystems & Nanoengineering, 2023
The particles of heterogeneous catalysts differ greatly in size, morphology, and most importantly, in activity. Studying these catalyst particles in batch typically results in ensemble averages, without any information at the level of individual catalyst

A lab-on-a-chip model of glaucoma [PDF]

Brain and Behavior, 2019
Abstract We developed a glaucoma-on-a-chip (GOC) model to evaluate the viability of retinal ganglion cells (RGCs) against high pressure and the potential effect of neuroprotection. A three-layered chip consisting of interconnecting microchannels and culture wells was designed based on simulation of physical parameters.
