In the current study, superparamagnetic magnetite nanoparticles were surface-modified with lactobionic acid (LA) to improve their intracellular uptake and ability to target hepatocytes. Maltotrionic acid (MA)-modified nanoparticles were also synthesized as a control. Cell culture experiment showed that LA-modified nanoparticles were internalized into hepatocytes and atomic absorption spectrometer...
Polyurethanes containing z-lysine segments in the main chain (PULL) were synthesized from 4,4′-diphenylmethyl diisocyanate, poly(tetramethylene glycol), and z-lysine oligomer as a chain extender. The PULL film was treated first with a 10% HBr-acetic acid solution and subsequently with a saturated sodium bicarbonate aqueous solution to produce a primary amine group on the surface (PULL-N). Lactobionic...
