Monodisperse 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...
متن کاملOptimization 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 کاملMolded polyethylene glycol microstructures for capturing cells within microfluidic channels.
The ability to control the deposition and location of adherent and non-adherent cells within microfluidic devices is beneficial for the development of micro-scale bioanalytical tools and high-throughput screening systems. Here, we introduce a simple technique to fabricate poly(ethylene glycol)(PEG) microstructures within microfluidic channels that can be used to dock cells within pre-defined lo...
متن کاملReusable, polyethylene glycol-structured microfluidic channel for particle immunoassays
A microfluidic channel made entirely out of polyethylene glycol (PEG), not PEG coating to silicon or polydimethylsiloxane (PDMS) surface, was fabricated and tested for its reusability in particle immunoassays and passive protein fouling, at relatively high target concentrations (1 mg ml(-1)). The PEG devices were reusable up to ten times while the oxygen-plasma-treated polydimethyl siloxane (PD...
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...
