Wound healing is a dynamic and complex process of replacing missing or dead cell structures and tissue layers. The aim of this research is to discover biocompatible materials and drugs that can promote cell migration in the wound area and thus enhance desirable wound healing effects. In this paper, we report that PDMS nanogratings could accelerate the migration of epithelial cells along the grating...
Conventional diagnosis based on ensemble measurements often overlooks the variation among cells. Here, we present a droplet-microfluidics based platform to investigate single cell activities. Adopting a previously developed isothermal rolling circle amplification-based assay, we demonstrate detection of enzymatic activities down to the single cell level with small quantities of biological samples,...
Conventional analysis of enzymatic activity, often carried out on pools of cells, is blind to heterogeneity in the population. Here, we combine microfluidics with a previously developed isothermal rolling circle amplification-based assay to investigate multiple enzymatic activities in down to single cells. This microfluidics-meditated assay performs at very high sensitivity in picoliter incubators...
