Optimization and Evaluation of Polyethylene Glycol Diacrylate as a Nonadsorptive Polymeric Material for Microfluidics
Polydimethylsiloxane (PDMS), commonly used in microfluidics, is susceptible to nonspecific adsorption of molecules and biological analytes, such as proteins. PDMS requires coating or chemical modification to overcome this problem. We optimized a single-monomer formulation of polyethylene glycol diacrylate (PEGDA), which upon polymerization to form polyPEGDA, provides reduced susceptibility to n...
متن کاملEvaluation of Polyethylene Glycol Diacrylate-Polycaprolactone Scaffolds for Tissue Engineering Applications
Polyethylene Glycol Diacrylate (PEGDA) tissue scaffolds having a thickness higher than 1 mm and without the presence of nutrient conduit networks were shown to have limited applications in tissue engineering due to the inability of cells to adhere and migrate within the scaffold. The PEGDA scaffold has been coated with polycaprolactone (PCL) electrospun nanofiber (ENF) membrane on both sides to...
متن کاملChitosan-polyethylene glycol coated cotton membranes for wound dressings
Membranes have been developed by coating a blend of chitosan (CS) and polyethylene glycol (PEG) of different molecular weights (4000, 10,000 and 20,000) on cotton fabric followed by freeze drying. The influence of PEG molecular weight on the physical characteristics of the membranes has been investigated. The scanning electron microscopy of the coated fabric reveals porous structure. The porosi...
متن کاملBiomechanical Performances of Networked Polyethylene Glycol Diacrylate: Effect of Photoinitiator Concentration, Temperature, and Incubation Time
Nutrient conduit networks can be introduced within the Polyethylene Glycol Diacrylate (PEGDA) tissue construct to enable cells to survive in the scaffold. Nutrient conduit networks can be created on PEGDA by macrochannel to nanochannel fabrication techniques. Such networks can influence the mechanical and cell activities of PEGDA scaffold. There is no study conducted to evaluate the effect of n...
متن کاملMonodisperse polyethylene glycol diacrylate hydrogel microsphere formation by oxygen-controlled photopolymerization in a microfluidic device.
PEG-based hydrogels have become widely used as drug delivery and tissue scaffolding materials. Common among PEG hydrogel-forming polymers are photopolymerizable acrylates such as polyethylene glycol diacrylate (PEGDA). Microfluidics and microfabrication technologies have recently enabled the miniaturization of PEGDA structures, thus enabling many possible applications for nano- and micro- struc...
