Application

Latex beads, amine-modified polystyrene, fluorescent blue has been used:
  • to study its effects on the concentration-response relationship of bacterial cell viability[1]
  • in the preparation of nanoparticles[2]
  • as a model nanoparticle to study interactions with human blood and platelets[3]

Biochem/physiol Actions

Polystyrene latex beads can be used to create latex agglutination systems. Polystyrene latex beads have been used to study the transmission of Mycobacterium leprae, the causative pathogen of leprosy, as well as to develop a method for mass screening for both pulmonary and extrapulmonary tuberculosis.

There is evidence that nanoparticles (NP) can enter the bloodstream following deposition in the lungs, where they may interact with platelets. Polystyrene latex nanoparticles (PLNP) of the same size but with different surface charge-unmodified (umPLNP), aminated (aPLNP), and carboxylated (cPLNP)-were

Questions

  1. What will be the concentration of plastics in 1ml? Can I add distilled water to make stock solution?

    1 answer

    1. The amine-modified polystyrene latex beads are suspended in distilled water with a minimum amount of proprietary cationic surfactant (0.2%). The concentration of solids (plastics) is >/= 2.5%.
