This paper reports the effect of L-lysine on the conformational, rheological, and thermal properties of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and N-hydroxysuccinimide (NHS) cross linked collagen and investigates the influence of l-lysine on the self assembly processes of collagen. In the absence of L-lysine, the rheological characterization of(More)
Iron oxide nanoparticles are being viewed with interest owing to the great potential they have in the biomedical applications like MRI contrast enhancement, targeted drug delivery, hyperthermia and recently in magnetic separation of cancer cells from the body. Templated synthesis has been considered ideal for synthesis of iron oxide nanoparticles as(More)
Thi s work reports a methodology for near complete mobilization and recovery of chromium from chromite ore process ing res idues. It has been found that it is possible to mobilize chromium from the residues. Vari ous factors which influence the ex tent of extraction of chromium from COPR have now been reported. An extracti on using sodium peroxide enables(More)
Chromium-containing wastes from various industrial sectors are under critical review. Leather processing is one such industrial activity that generates chromium-bearing wastes in different forms. One of them is chrome shavings, and this contributes to an extent of 10% of the quantum of raw skins/hides processed, amounting to 0.8 million ton globally. In(More)
The contamination of soil and wastewaters with Cr(VI) is a major problem. It has been suggested that microbial methods for Cr(VI) reduction are better than chemical methods, as they do not add other ions or toxic chemicals to the environment. In this study an aerobic reduction of Cr(VI) to Cr(III) by employing mixed Pseudomonas cultures isolated from a(More)
The use of nano-particles in several areas necessitates the understanding of their interaction with cells, tissues and experimental animals. In the present study, the effect of a curcumin conjugated gold nano-particle on peripheral blood lymphocytes was investigated. The treated lymphocytes revealed features typical of apoptosis which include chromatin(More)
Ever since the ability of laccase to oxidize non-phenolic lignin models was described, the oxidative degradation reactions catalyzed by laccase have been widely studied for paper pulp production or detoxification of aromatic pollutants. The viability of developing eco-friendly, laccase aided industrial processes has been explored. Here, we report the(More)
Stabilization of collagen for various applications employs chemicals such as aldehydes, metal ions, polyphenols, etc. Stability against enzymatic, thermal and mechanical degradation is required for a range of biomedical applications. The premise of this research is to explore the use of nanoparticles with suitable functionalization/encapsulation to(More)
The processing of chromite ore is associated with the generation of large quantities of solid wastes containing chromium, which have been disposed of as landfill for many years. The mobilization and operational speciation of chromium contained in soils contaminated with metal salts are important in terms of the environment. Several methods have been(More)
Creating collagen scaffolds that mimic extracellular matrices without using toxic exogenous materials remains a big challenge. A new strategy to create scaffolds through end-to-end crosslinking through functionalized nanorods leading to well-designed architecture is presented here. Self-assembled scaffolds with a denaturation temperature of 110 °C, porosity(More)
