AB  - A simple and green chemical method has been developed to synthesize stable bare and capped silver nanoparticles based on the reduction of silver ions by glucose and capping by poly(α,γ,l-glutamic acid) (PGA). The use of ammonia during synthesis was avoided. PGA has had a dual role in the synthesis and was used as a capping agent to make the silver nanoparticle more biocompatible and to protect the nanoparticles from agglomerating in the liquid medium. The synthesized PGA-capped silver nanoparticles in the size range 5–45 nm were stable over long periods of time, without signs of precipitation. Morphological examination has shown that the silver nanoparticles had a nearly spherical, multiply twinned structure. The effects of the reaction temperature and the reaction time during the synthesis were investigated too. The biocompatibility of the PGA-capped silver nanoparticles is discussed in terms of in vitro toxicity with human intestinal Caco-2 cells. The samples were characterized by UV–Visible spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, and zeta potential measurements.

AB  - Owing to their persistent antibacterial properties, Ag nanoparticles are increasingly used in clinical practice and investigated in recent laboratory research. Although there are a number of methods for the synthesis of Ag nanoparticles, recent research trends comply with the requirements of Non-toxic Environmental Chemistry. In this study, the synthesis of silver nanoparticles was based on the principles of green chemistry. In order to improve their antibacterial properties and biocompatibility, Ag nanoparticles can be coated with various biocompatible and biodegradable polymers that can ensure their better interaction with cells and more favourable size distribution. Poly(α, γ-glutamic acid) is one of the polymers that have the required properties; it also serves as particle stabilizer. The synthesis of Ag nanoparticles was performed by a modified chemical reduction method with glucose as the reducing agent. The samples were characterized by UV/ Vis spectroscopy, FESEM and Zeta potential measurements

AB  - Hidroksiapatit, HAp, Ca10(PO4)6(OH)2, je materijal koji se, zahvaljujući svojoj biokompatibilnosti, često koristi u regeneraciji koštanog tkiva. Usled česte pojave infekcije, koja može nastati njegovom ugradnjom, primenjuje se hidroksiapatit supstituisan srebrom, koji ima dokazane antibakterijske osobine. Cilj ovog rada je sinteza HAp-a, čija struktura sadrži atome srebra, metodom precipitacije u vodenom rastvoru. Karakterizacija materijala je vršena ispitivanjem faznog sastava XRD analizom, ispitivanje morfologije čestica metodom SEM-a, hemijskog sastava ICP analizom i merenjem raspodele veličina čestica. Rendgenska difrakcija na polikristalnim uzorcima HAp-a sa manjim sadržajima srebra (0,5; 1; 2 at %) potvrdila je monofazni karakter sintetisanih prahova. Međutim, povećanje sadržaja Ag+ jona u kristalnim prahovima HAp-a uslovljava pojavu novih refleksija na difraktogramima, koje odgovaraju srebro-fosfatu.
