Antimicrobial activity of silver nanoparticle impregnated bacterial cellulose membrane: Effect of fermentation carbon sources of bacterial cellulose

Green Synthesis of Silver Nanoparticles using Aqueous Plant Extracts and its Application as Optical Sensor

“…Nanoparticles were found to be get agglomerated above pH 8. 3 The FTIR peaks (Figure 4) at 3339.69cm -1 shows the presence of OH groups and 1634.87cm -1 , C=0 groups. 4 Thus, the presence of C=O groups and OH groups indicates that it can be attached to cellulose matrix having high concentration of hydroxyl group.…”

“…Now, it was filtered out and secured. Whatman filter paper (Grade 1) was used for the filtration The leaf extract (2, 3, 4, 5, 10, 15, 20ml) was added to a vigorously stirred 30ml solution of 1*10 -4 M AgNO 3 . Stirring continued for 30 min to get the colloids labelled c1 to c6.…”

“…[1][2][3][4][5] Nanoparticles are also interesting because of their huge increase in surface area and a surge in conductivity compared to their metal counterparts. Moreover, metal nanoparticles also show surface plasmon resonance.…”

“…These properties make them useful to many applications such as bio-sensing, imaging, drug delivery, HIV treatment, Cancer treatment, optical spectroscopy and Surface Enhanced Raman scattering (SERS). [2][3][4] Amongst different type of metal nanoparticles Ag NPs (Silver nanoparticles) are of great interest due to their potent antimicrobial activity against different type of pathogens. [6][7][8][9][10] This extends their application into medicine, wound healing, dental materials, coating of stainless steel material, water treatment, sunscreen lotions, elimination of microorganisms on textile fabrics, cosmetics, optical transparent composites, polymer composites etc.…”

Preparation and Characterization of Bacterial Cellulose Composites with Silver Nanoparticles

“…by mechanically mixing the polymer with metal nanoparticles in the form of powder or suspension, with the polymerization of the monomers in situ in the presence of metal nanoparticles, or by chemical reduction, for example sodium borohydride (Yang et al, 2012a;Wua et al, 2015).…”
