| Abstract (English): |
Due to their easy and low-cost production and enhanced properties, noble metal nanoparticles are preferred as nano-additives in most pharmaceutical compositions. For example, silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) possess antiseptic and antimicrobial activity and they are generally preferred for obtaining antibacterial clothing and coatings. In the present study, we report a simple, low cost and green method for synthesizing AgNPs using aqueous extracts of common poppy (Papaver rhoeas L). Synthesised silver nanoparticles were characterised based on Field Emission Scanning Electron Microscopy equipped with energy dispersive X-ray spectroscopy, Fourier-Transform Infrared Spectroscopy, and X-ray diffraction analysis. The synthesised AgNPs were also tested for antimicrobial activity using the agar well diffusion method. Characterisation methods showed that the obtained AgNPs were spherical in shape, with a particle size ranging from 15 to 40 nm. According to the antimicrobial test results, AgNPs effectively inhibited the growth of various gram-positive and gram-negative bacteria. It was concluded that Papaver rhoeas L. extract is effective as a reducing agent for the preparation of stable and monodispersed AgNPs and obtained AgNPs could be useful in antibacterial applications in human and veterinary medicine.

| Abstract (Croatian): |
Zahvaljujući njihovoj jednostavnoj i jeftinoj proizvodnji i pojačanim svojstvima, nanočestice plemenitih metala preferirani su nano-aditivi u većini farmaceutskih spojeva. Na primjer, nanočestice srebra (AgNP) i nanočestice zlata (AuNP) posjeduju antiseptička i antimikrobna svojstva i općenito se preferiraju u proizvodnji antibakterijske odjeće i premaza. U ovoj studiji donosimo jednostavnu, jeftinu i zelenu metodu sintetiziranja AgNP čestica uporabom vodenih ekstrakata maka turčinaka (Papaver rhoeas L.). Sintetizirane nanočestice srebra okarakterizirane su na temelju pretražne mikroskopije emisijom elektrona primjenom polja (Field Emission Scanning Electron Microscopy) opremljene energetski disperzivnom RTG spektroskopijom, infracrvenom spektroskopijom s Fourierovom transformacijom i rendgenskom difrakcijskom analizom. Sintetizirane AgNP čestice ispitane su i na antimikrobnu aktivnost uporabom metode difuzije u agaru. Metode karakterizacije pokazale su da su dobivene AgNP čestice sfernog oblika, a veličina čestica kretala se između 15 i 40 nm. Prema rezultatima antimikrobnih ispitivanja, AgNP čestice učinkovito su spriječile rast različitih gram-pozitivnih i gram-negativnih bakterija. Zaključeno je da je ekstrakt Papaver rhoeas L. učinkovit kao reducens za pripremu stabilnih i monodisperziranih AgNP čestica, a dobivene AgNP čestice mogle bi biti korisne za primjene u humanoj i veterinarskoj medicini kada je potreban antibakterijski učinak.
