Hemolysis of human erythrocytes as a function of time of exposure to 47.4-54.5 degrees C was measured and correlated to thermal transitions in the membranes of intact erythrocytes as determined by differential scanning calorimetry (DSC). Curves of hemoglobin leakage (a measure of hemolysis) as a function of time have a shoulder region exhibiting no leakage,(More)
Pharmacologically active stem of the oriental herbal adaptogen, Siberian ginseng, was employed for the ecofriendly synthesis of Siberian ginseng silver nanoparticles (Sg-AgNPs) and Siberian ginseng gold nanoparticles (Sg-AuNPs). First, for metabolic characterization of the sample, liquid chromatography-tandem mass spectrometry analysis (indicated the(More)
A straightforward synthesis of gold nanoparticles (AuNps) is achieved by novel probiotic Lactobacillus kimchicus DCY51T isolated from Korean kimchi via an intracellular membrane-bound mechanism. The bioreduction of HAuCl4 into AuNps was verified by ultraviolet-visible spectrophotometry at ∼540nm. AuNps were spherical with varying sizes of 5-30nm. AuNps(More)
The current study highlights the rapid biosynthesis of gold nanoparticles (Gu-AuNps) and silver chloride nanoparticles (Gu-AgClNps) by aqueous root extract of Glycyrrhiza uralensis, a medicinal plant. G. uralensis has been reported for anticancer and hepatoprotective effects. The reduction of chloroauric acid and silver nitrate by the Glycyrrhiza root(More)
Green synthesis of gold (CB-AuNps) and silver (CB-AgNps) nanoparticles using Cibotium barometz root extract was highlighted. CB-AuNps were synthesized almost instantly and CB-AgNps were formed after 25 min in a heated aqueous extract. The formation of CB-AuNps and CB-AgNps was detected at 548 and 412 nm; they were spherical with crystallite sizes of 6 nm(More)
The design of mild and non-toxic synthesis of metallic nanoparticles is a topical subject in the nanotechnology field. The objective of this present study is to screen the bioactivity of biosynthesized nanoparticles by aqueous fruit extract of Chaenomeles sinensis. The reducing and stabilizing ability of C. sinensis to fabricate gold (Cs-AuNps) and silver(More)
A facile synthesis and biological applications of silver (DH-AgNps) and gold nanoparticles (DH-AuNps) mediated by the aqueous extract of Angelicae Pubescentis Radix (Du Huo) are explored. Du Huo is a medicinal root belonging to Angelica pubescens Maxim which possesses anti-inflammatory, analgesic, and antioxidant properties. The absorption spectra of(More)
Gold (FA-AuNps) and silver (FA-AgNps) nanoparticles were synthesized at room temperature by aqueous extract of dried fruits of Amomum villosum, also known as Fructus Amomi (cardamom), in order to confer antioxidant, catalytic, antimicrobial activities and treatment effect against breast cancer cells. Fruit extracts served as both reducing agents and(More)
A rapid biological synthesis of multifunctional gold nanoparticle (AuNp) and monodisperse silver nanoparticle (AgNp) was achieved by an aqueous extract of black Panax ginseng Meyer root. The physicochemical transformation into black ginseng (BG) greatly enhanced the pharmacological activities of white ginseng and its minor ginsenoside content. The optimal(More)
There has been a growing interest in the design of environmentally affable and biocompatible nanoparticles among scientists to find novel and safe biomaterials. Panax ginseng Meyer berries have unique phytochemical profile and exhibit beneficial pharmacological activities such as antihyperglycemic, antiobesity, antiaging, and antioxidant properties. A(More)
