Abstract

Nanotehnologija se polako ali sigurno uvlači u svakodnevicu čovjeka 21. stoljeća, a zlatne nanočestice prednjače u takozvanoj nanorevoluciji. Iako su ljudima poznate još od antičkog doba, tek im se unazad 10-ak godina počela pridavati veća važnost. Razlog tome su, osim samog razvoja nanotehnologije, izvrsna svojstva zlatnih nanočestica. S obzirom da dosadašnje metode sinteze daju nusprodukte štetne za okoliš, znanstvenici intenzivno rade na pronalasku metoda koje će imati što manji utjecaj na okoliš. Princip koji podrazumijeva upotrebu vodenih otapala, prirodnih reagensa i blagih uvjeta sinteze zovemo zelenom ili biosintezom. Jedna takva metoda sinteze predstavljena je kroz prikaz objavljenog znanstvenog istraživanja u ovom radu. Zbog svojih brojnih, raznolikih i jedinstvenih svojstava, nanočestice zlata nalaze primjenu u medicinskoj dijagnostici, terapijskom liječenju karcinoma, dopremi lijekova, senzorima, katalizi i brojnim drugim poljima znanosti.

Abstract (english)

Nanotechnology is slowly but surely creeping into the everyday life of 21st century man, and gold nanoparticles are at the forefront of the so-called nanorevolution. Although they have been known to people since ancient times, it was only 10 years ago that they began to be given more importance. The reasons for this, in addition to the development of nanotechnology, are the excellent properties of gold nanoparticles. Since the conventional methods of synthesis produce by-products harmful to the environment, scientists are working intensively to find methods that will have the decrease this negative influence. The principle that involves the use of aqueous solvents, natural reagents and mild synthesis conditions is called green or biosynthesis. One method of biosynthesis is presented through presentation of published scientific research in this paper. Due to their numerous, diverse and unique properties, gold nanoparticles are used in medical diagnostics, therapeutic treatment of cancer, drug delivery, sensors, catalysis and many other fields of science.
