Biogenic Selenium Nanoparticles: A Fine Characterization to Unveil Their Thermodynamic Stability

Adsorption of zinc by biogenic elemental selenium nanoparticles

Biogenic Synthesis and Characterization of Selenium Nanoparticles Using the Flower of Bougainvillea spectabilis Willd

The present study reports that the flower of Bougainvillea spectabilis Willd. has the potentiality to reduce sodium selenate and synthesize selenium nanoparticles. The exposure of aqueous sodium selenate to the flower broth of B.spectabilis leads to the synthesis of stable selenium nanoparticles within five days. The colour change of the reaction medium from purple to brown colour indicates the...

Biogenic selenium nanoparticles: characterization, antimicrobial activity and effects on human dendritic cells and fibroblasts

Tailored nanoparticles offer a novel approach to fight antibiotic-resistant microorganisms. We analysed biogenic selenium nanoparticles (SeNPs) of bacterial origin to determine their antimicrobial activity against selected pathogens in their planktonic and biofilm states. SeNPs synthesized by Gram-negative Stenotrophomonas maltophilia [Sm-SeNPs(-)] and Gram-positive Bacillus mycoides [Bm-SeNPs(...

Biogenic Synthesis of Silver Nanoparticles Using Mustard and Its Characterization

The field of nanobiotechnology mainly encompasses with physics, biology, chemistry and material sciences and it develops novel therapeutic nano-scale materials for biomedical, drug delivery, cancer therapy and pharmaceutical applications. Silver nanoparticles (AgNPs) have unique physiochemical, biological and environmental properties which make them useful in a wide range of applications, s...

Th1 Immune Response Induction by Biogenic Selenium Nanoparticles in Mice with Breast Cancer: Preliminary Vaccine Model

Background: Tumor associated antigens can be viably used to enhance host immune response. Objectives: The immunomodulatory effect of biogenic selenium nanoparticles (SeNPs) was compared between treated and untreated mice with crude antigens of 4T1 cells. Materials and Methods: Female inbred BALB/c mice (60) were injected by cancinogenic 4T1 cells causing breast cancer. After 10 days, all tumor ...
