“…A light gray colloidal AgNPs solution was obtained. RSP ranging from 320 to 420 nm, with a pronounced peak of maximum absorbance at 390 nm, was noted in UV-Vis spectroscopy, indicating the formation of AgNPs measuring 5-50 nm, as inferred by wavelength width [43]. Additionally, TEM revealed that AgNPs were spherical.…”

Background: The presence of skin problems in patients using external lower limb prosthesis is recurrent. This has generated the need to develop interfaces for prosthesis with the ability to control microbial growth. Silver nanoparticles (AgNPs) have been implemented in the development of biomaterials because of their high antimicrobial activity. This article discusses the development of an AgNP-containing polymer composite with antimicrobial activity for developing prosthetic liners. Methods: AgNPs were synthesized using a photochemical method and certain physicochemical properties were characterized. Furthermore, the antimicrobial activity of AgNPs against Staphylococcus aureus ATCC 25923 and methicillin-resistant Staphylococcus aureus (MRSA), was assessed on the basis of their minimum inhibitory concentrations (MICs). AgNPs were incorporated into a silicon elastomer to assess certain physicomechanical properties, antimicrobial activity and cytotoxic effect of the material. Results: The maximum antimicrobial activity of the material against Staphylococcus aureus ATCC 25923 and MRSA was 41.58% ±2.97% at AgNP concentration of 32.98 μg/mL and 14.85% ±5.94% at AgNP concentration of 16.49 μg/mL, respectively. Additionally, the material exhibited tensile yield strength, rupture tensile strength, and tensile modulus of elasticity of 0.70-1.10 MPa, 0.71-1.06 MPa, and 0.20-0.30 MPa, respectively. The mechanical characteristics of the material were within the acceptable range for use in external lower limb prosthetic and orthotic interfaces. Conclusions: It was possible to incorporate the AgNPs in a silicone elastomer, finding that the composite developed presented antimicrobial activity against Staphylococcus aureus ATCC 25923 and MRSA when compared to non-AgNP material samples.

“…The reduction process begins with the colour change from transparent to pale yellow, which showed the formation of Ag NPs. The nanoparticle solution was stirred (10, 15 and 20 min) on a magnetic stirrer at 90°C and stored in refrigerator (8±1°C) for further stability study [9].…”

The present work was aimed to study the synthesis of silver nanoparticles (Ag NPs) using Tri-Sodium Citrate (TSC), stability study of synthesized Ag NPs and their characterization. Synthesis of Ag NPs has been carried out by maintaining different conditions such as TSC concentration (0.50, 1.00 and 1.50%), AgNO3 concentration (0.50, 1.00 and 1.50 mM) and stirring time (10, 15 and 20 min). The stability study of synthesized Ag NPs conducted for 30 days without adding any stabilizing agents. The characterization of synthesized Ag NPs was carried out for different parameters like particle size and zeta potential using particle size analyzer, absorbance peak by UV-Visible spectrophotometer, morphology by Scanning Electron Microscope (SEM), crystallinity by X-Ray Diffractometer (XRD) and material structural characteristics by Atomic Force Microscope (AFM). The stable chemically synthesized Ag NPs were obtained at C20 (AgNO3 concentration of 1.5 mM, TSC 1.5% and stirring time 20 min) (desirability 99.97%), with average particle size of 22.14 nm and average absorbance peak of 449.85 nm.

“…In this equation, the positive values indicate a favourable effect of the parameter on the response, whereas the negative values represent an antagonistic effect on the response (an inverse relationship); moreover, the magnitude of these numbers shows the extent of the impact of each factor. 27,28 As eqn (2) indicates, the positive sign for A and D allow the particles to have a smaller size. In addition, the magnitude of coefficient indicates that the impact of D is far more than that of A.…”
