The topic of this investigation was to evaluate the microbial contamination of household sponges, biosynthesize of silver nanoparticles (Ag NPs) by Gliocladium deliquescens cell-free supernatant, and estimate the efficiency of Ag NPs as an acceptable disinfectant. The 23 factorial design was applied for the optimization of Ag NPs synthesis. Silver ...

Biological methods offer eco-friendly and cost-effective alternatives for the synthesis of silver nanoparticles (AgNPs). The present study highlights a green process where AgNPs were synthesized and optimized by using silver nitrate (AgNO3) and the aqueous extract of Piper betle (Pbet) leaf as the reducing and capping agent. The stable and optimize...

The in vitro cytotoxicity of nano silver nanoparticles (nAg, 99 ± 75 nm) and nano zinc oxide nanoparticles (nZnO, 27 ± 7 nm) pretreated with citric acid (CA), tartaric acid (TA), and fulvic acid (FA) to human pulmonary adenocarcinoma cells (A549 cells), a common model cell strain, was investigated. The LC50 values of CA-, FA-, and TA-nZnO (19–22 μg...

A novel online coupling of microchip isotachophoresis (μITP) with surface-enhanced Raman spectroscopy (SERS) for the analysis of complex samples is presented. Polymeric microchip with coupled channels was used for μITP-SERS analysis of four structurally similar Raman active synthetic dyes (brilliant black BN, carmoisine, ponceau 4R, and sunset yell...

BackgroundDimorphism and biofilm formation are important virulence factors of some opportunistic human pathogenic yeasts. Such species commensally colonize skin or mucosal surfaces generally in yeast form, but under particular circumstances, convert into virulent hyphae and disseminate internal organs or cause mucocutaneous infections. The yeast-to...

BackgroundThe emergence and expansion of antibiotic resistance makes it necessary to have alternative anti-infective agents, among which silver nanoparticles (AgNPs) display especially interesting properties. AgNPs carry out their antibacterial action through various molecular mechanisms, and the magnitude of the observed effect is dependent on mul...

Treatment of cancer has been limited by the poor efficacy and toxicity profiles of available drugs. There is a growing demand to develop alternative approaches to combat cancer such as use of nano-formulation-based drugs. Here, we report biosynthesis and characterization of silver nanoparticles (AgNPs) with papaya leaf extract (PLE) and its anti-ca...

Synergistic effects occurring between biologically active substances are of great importance for efficient treatment of many diseases. Therefore, the aim of research was to determine impact of sodium hexametaphosphate (HEX), which is a well-known permeabilizer, on the cytotoxicity of silver ions and two types of AgNPs towards HL-60 and U-937 tumor ...

The seaweed Kappaphycus striatus is a well-known source of carrageenan and other valuable bioactive compounds. Tto improve the efficiency of propagation of this important natural resource, we studied the aseptic efficiency of silver nanoparticles (AgNPs) in the explant sterilization process. We further evaluated the effects of culture media, plant ...

The influence of polymeric shell formed by the layer-by-layer (LbL) assembly technique using chitosan or its grafted copolymers with dextran or poly(ethylene glycol) and dextran sulfate on physico-chemical properties and aggregation kinetics of silver nanoparticles (AgNP) was investigated. It is shown that the hydrodynamic diameter of encapsulated ...
