Anwendung

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

Biochem./physiol. Wirkung

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

Recent studies indicate that inhaled ultrafine particles can pass into the circulation. To study this translocation in an in vitro model three types of pulmonary epithelial cells were examined. The integrity of the cell monolayer was verified by measuring the
