General description

Poly(acrylic acid) solution (PAA) is an anionic polymer that can be synthesized by the free radical polymerization of acrylic acid. It has a swelling nature that tends to absorb and retain the water. It has a high ion exchange capacity that makes it useful in the development of membranes.

Application

PAA can be used for a variety of applications such as:
  • a surfactant in the formation of photonic crystals
  • a binder for the development of Silicon anode based lithium ion batteries
  • polyelectrolyte membranes for electronics and optoelectronics based applications

Magnetic-Plasmonic Hybrid Nanobeads Designed for Imaging and Isolation of Cellular Organelles

Magnetic-plasmonic nanoparticles offer the combined benefits of both a magnetic probe as well as additional imaging modes usually associated with noble metal nanoparticles. Professor Shinya Maenosono (Japan Advanced Institute of Science and Technology) explores the synthesis, characterization, and proof-of-concept application of Ag/FeCo/Ag core/shell/shell magnetic-plasmonic nanobeads for imaging and isolation of cellular organelles (autophagosomes of COS-1 cells).
