Ce este platina coloidala?
Platina coloidala consta intr-o suspensie de particule fine de platina suspendate intr-un lichid. Nanoparticulele sunt definite ca particule coloidale solide care pot varia in dimensiune de la 10 nm la 1,0 mm. Sistemele coloidale pentru dispersia metalelor ofera avantajul dimensiunii mici (1-50 nm diametru) care permite o absorbtie usoara.
Care sunt potentialele beneficii ale platinei coloidale?
Nanoparticulele de platina au aplicatii biomedicale, inclusiv in imagistica, implanturi, terapie fototermala si cedarea unor substante active.
Intr-adevar, nanoparticulele de platina pot poseda si proprietati intrinseci antimicrobiene, antioxidante si anticancerigene.
Care sunt potentialele reactii adverse ale nanoparticulelor de platina?
Exista studii care au demonstrat ca nanoparticulele de platina au cauzat leziuni morfologice, inclusiv inflamatie si deteriorare celulara.
