Abstract
U ovom radu proučavana je sinteza nanočestica koloidnog srebra dobivenih pomoću meda od primorskog vriska (Satureja montana) s dalmatinskog područja, te određena antibakterijska vrijednost dobivenog koloidnog srebra. Kao izvor srebra korišten je srebrov nitrat, a pH vrijednost otopine meda je podešena s 3,53 na 6 s otopinom natrijeva karbonata. Sinteza je provedena pri 20 °C uz miješanje. Prvi dokaz nastanka koloidnog srebra bilo je određivanje intenziteta Tyndallova efekta uslijed propuštanja laserske zrake kroz koloide. UV–Vis spektrofotometrom u području valnih duljina 330-500 nm, SEM (Scanning Electron Microscope) analizom i DLS metodom izvršena je karakterizacija uzoraka nastalog koloidnog srebra. Antibakterijska efikasnost koloidnog srebra testirana je uz pomoć bakterija Escherichia coli NCTC 13216 i Staphylococcus aureus ATCC 25923. Dokazano je antibakterijsko djelovanje koloidnog srebra dobivenog pomoću meda od primorskog vriska (Satureja montana) za ove dvije bakterije do određenih koncentracija.
Abstract (english)
In this work, the synthesis of colloidal silver nanoparticles using mountain savory (Satureja montana) honey from the Dalmatian region was studied, and the antibacterial activity of the resulting colloidal silver was determined. Silver nitrate was used as a source of silver, and the pH value of honey solution was adjusted from 3.53 to 6 with a solution of sodium carbonate. The synthesis was carried out at 20 °C with mixing. The first evidence of colloidal silver was the determination of the intensity of the Tyndall effect by passing a laser beam through the colloids. UV-Vis spectrophotometer in the area of wavelengths 330-500 nm, SEM (scanning electron microscopes) analysis and DLS method was performed characterization of samples of colloidal silver. The antibacterial efficiency of colloidal silver was tested with the help of Escherichia coli NCTC 13216 and Staphylococcus aureus ATCC 25923. It was demonstrated the antimicrobial activity of colloidal silver obtained by using mountain savory (Satureja montana) honey for these two bacteria up to certain concentrations.
