| Abstract (English): |
Green Synthesis of Nanoparticles is a novel field of nanotechnology that outperforms both biological and chemical approaches in terms of biocompatibility, cost-efficiency, scalability and environmental friendliness. Bacteria, fungi, plant and algae have lately been used to produce metals and metal oxide nanoparticles as an alternate method. In the present study, the green synthesis of Silver and copper nanoparticles was carried out using leaf extract of Emblica officinalis as a reducing agent and their antibacterial activity against human pathogens. Biosynthesis of nanoparticles were carried out using methanolic leaves extract of Emblica officinalis. Nanoparticles were characterized by UV-Visible Spectroscopy, X-ray Diffraction patterns(XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). These biogenic particles were tested for antimicrobial activity by disc diffusion method against Escherichia coli & Staphylococcus aureus. Biosynthesized nanoparticles showed potent biological activity and effective radicals scavenging activity. Methanolic leaf extract of Emblica officinalis acts as an excellent capping agent for the formation of silver & copper nanoparticles and demonstrates immense biological activities. Hence, these particles can be used as antibacterial, antioxidant as well as cytotoxic agent in treating many medical complications. It can be concluded that the silver and copper nanoparticles constitute an effective antimicrobial agent against common pathogenic bacteria. This could be a significant achievement in contending with many dynamic pathogens. [ABSTRACT FROM AUTHOR] |
| Abstract (Bosnian): |
Zelena sinteza nanočestica je nova oblast nanotehnologije koja nadmašuje i biološke i hemijske pristupe u smislu biokompatibilnosti, ekonomičnosti, skalabilnosti i ekološke prihvatljivosti. Bakterije, gljive, biljke i alge se u poslednje vreme koriste za proizvodnju metala i nanočestica metalnih oksida kao alternativne metode. U ovoj studiji, zelena sinteza nanočestica srebra i bakra je sprovedena korišćenjem ekstrakta lista Emblica officinalis kao redukcionog agensa i njihove antibakterijske aktivnosti protiv ljudskih patogena. Preliminarna fitohemijska analiza metanolnog ekstrakta E.officinalis pokazala je prisustvo tanina, saponina, flavanoida i fenola, od kojih su flavonoidi i saponini najinhibitivniji prema svim patogenima. Emblica officinalis definitivno poseduje snažno antimikrobno dejstvo protiv bakterijskih patogena i može se koristiti u lečenju različitih bolesti izazvanih ovim organizmima. Biosinteza nanočestica je sprovedena korišć enjem metanolnog ekstrakta listova Emblica officinalis. Nanočestice su okarakterisane UV-vidljivom spektroskopijom, uzorcima difrakcije rendgenskih zraka (XRD), skenirajućom elektronskom mikroskopijom (SEM) i transmisijskom elektronskom mikroskopijom (TEM). Ove biogene čestice su testirane na antimikrobnu aktivnost metodom disk difuzije protiv Escherichia coli i Staphilococus aureus. Biosintetizovane nanočestice pokazale su snažnu biološku aktivnost i efikasnu aktivnost uklanjanja radikala. Metanolni ekstrakt lista Emblica officinalis deluje kao odlično sredstvo za zatvaranje za formiranje nanočestica srebra i bakra i pokazuje ogromne biološke aktivnosti. Stoga se ove čestice mogu koristiti kao antibakterijski, antioksidativni, kao i citotoksični agens u lečenju mnogih medicinskih komplikacija. Može se zaključiti da nanočestice srebra i bakra predstavljaju efikasan antimikrobni agens protiv uobičajenih patogenih bakterija. [ABSTRACT FROM AUTHOR] |
