In the same study, SPARTA® provided single particle verification of sequential disulfide exchange surface functionalisation of polystyrene nanoparticles. Conclusions Nanoformulations offer a versatile platform for drug delivery to improve biodistribution, biostability and targeting potential compared to ...
Two addition‐type polymers, polystyrene and polypropylene, and two condensation‐type polymers, poly(ethylene terephthalate) (Mylar) and poly(hexamethylene adipamide) (nylon‐6,6), were pyrolyzed directly in the ion source of a mass spectrometer by chemical ionization (CI) to reduce fragmentation....
H2O, acetic acid, sunflower oil, heptane, and the amt of photostabilizer eluted was determined by spectrophotometry and by gas chromatography. The elution of 2-hydroxy-4-n-octyloxybenzophenone depended on the type of plastic. Elution was low in polystyrene and high in polyolefins, polyethylene. ...
