On-line production of polyelectrolyte coating on monodisperse alginate beads in an integrated microfluidic cartridge

Laffite G., Forvi E., Hadji C., Authesserre C., Alessio M., Costa G., Boizot F., Rivera F., CEA-LETI, FR

Continuous flow microfluidic devices have appeared to be a promising technology to automatise Polyelectrolytes multilayers (PEMs) coating on microbeads with repeatable and reliable results. However, no microfluidic devices have demonstrated PEMs coating on hydrogel beads [...]

Formation of complex nanoparticles from a spherical protein (BSA) and two polycations (PDL with two molecular weights) using coacervation method of the polyelectrolytes

Maldonado L., Sadeghi R., Kokini J., Purdue University, US

Complex nanoparticles (CNPs) were formed by mixing Bovine Serum Albumin (BSA) and Poly-D-Lysine with low (LMW-PDL) and high molecular weights (HMW-PDL). Since BSA and both PDL biopolymers in neutral and alkaline pHs are oppositely charged [...]

Polymer nanoparticles as nanoformulation agents

Pham H., Li F., Goh J.B., Dinglasan J., Anderson D., Vive Nano, Inc., CA

An approach to produce polymer nanoparticles with tailored characteristics to accommodate different nanoformulation applications is presented. Polymer nanoparticles are made from the collapse of polyelectrolytes in the presence of counterions and/or different solvents. The size, [...]

Nanoparticle synthesis using polyelectrolyte nanoreactors

Anderson D.J., Dinglasan J., Goh J.B., Goh M.C., Veletanlic E., Goh J.B., Goh M.C., Vive Nano, CA

We report a facile method to synthesize a wide range of nanoparticles via polyelectrolyte nanoreactors. The nanoreactors are formed through ion-induced collapse of highly extended, high molecular weight anionic polyelectrolytes using metal salts. The formation [...]
