Fluorescent Contrast agent Based on Graphene Quantum Dots Decorated Mesoporous Silica Nanoparticles for Detecting and Sorting Cancer Cells

Background and Objectives: The inability of classic fluorescence-activated cell sorting to single cancer cell sorting is one of the most significant drawbacks of this method. The sorting of cancer cells in microdroplets significantly influences our ability to analyze cancer cell proteins. Material and Methods: We adapted a developed microfluidic device as a 3D in vitro model to sorted MCF-7 c...

Droplet-based 3d Graphene Structure Synthesis

In this study, we presented a droplet-based microfluidic system for synthesizing three-dimensional (3D) graphene structure, called graphene popcorn. The droplets that were obtained by varying the flow rates and the concentration of graphene oxide (GO) solution were incubated in the furnace for rapid evaporation, resulting in the reduction of the GO as well as the aggregation of GO to form the g...

Preparation and Characterization of an Antifouling Polyethersulfone Nanofiltration Membrane Blended with Graphene Oxide/Ag Nanoparticles

Graphene oxide/Ag nanoparticles (Ag/GO) was prepared and employed to synthesize antifouling polyethersulfone (PES) mixed matrix membranes. The performance of the membranes was evaluated in terms of flux, hydrophilicity and anti-biofouling properties. With increment of the Ag/GO from 0 to 0.1 wt.%, the pure water flux increased from 24.7 up to 54.1 kg/m2 h. The flux recovery ratio (FRR) of the m...

Numerical Study of Droplet Generation Process in a Microfluidic Flow Focusing

Microfluidic flow focusing devices have been utilized for droplet generation on account of its superior control over droplet size.
