Inhibition of Glycation-Induced Aggregation of Human Serum Albumin by Organic-Inorganic Hybrid Nanocomposites of Iron Oxide-Functionalized Nanocellulose.

Protein aggregation leads to the transformation of proteins from their soluble form to the insoluble amyloid fibrils and these aggregates get deposited in the specific body tissues, accounting for various diseases. To prevent such an aggregation, organic-inorganic hybrid nanocomposites of iron oxide nanoparticle (NP, ∼6.5-7.

Nanomaterials as potential and versatile platform for next generation tissue engineering applications.

Tissue engineering (TE) is an emerging field where alternate/artificial tissues or organ substitutes are implanted to mimic the functionality of damaged or injured tissues. Earlier efforts were made to develop natural, synthetic, or semisynthetic materials for skin equivalents to treat burns or skin wounds. Nowadays, many more tissues like bone, cardiac, cartilage, heart, liver, cornea, blood vessels, and so forth are being engineered using 3-D biomaterial constructs or scaffolds that could deliver active molecules such as peptides or growth factors.

Toxicity Concerns of Therapeutic Nanomaterials.

In the modern era, research on the synthesis of nanoparticles (NPs) has been growing exponentially. Due to their small size together with extra-ordinary physico-chemical properties, a variety of NPs i.e.

Cytocompatible Anti-microbial Dressings of Syzygium cumini Cellulose Nanocrystals Decorated with Silver Nanoparticles Accelerate Acute and Diabetic Wound Healing.

The ever increasing incidences of non-healing skin wounds have paved way for many efforts on the convoluted process of wound healing. Unfortunately, the lack of relevance and success of modern wound dressings in healing of acute and diabetic wounds still remains a matter of huge concern. Here, an in situ three step approach was embraced for the development of nanocomposite (NCs) dressings by impregnating silver nanoparticles (AgNPs) onto a matrix of cellulose nanocrystals (CNCs) isolated from Syzygium cumini leaves using an environmental friendly approach.

In vivo diabetic wound healing potential of nanobiocomposites containing bamboo cellulose nanocrystals impregnated with silver nanoparticles.

In diabetes, hyperglycemic state immensely hinders the wound healing. Here, nanobiocomposites (NCs) developed by impregnation of in situ prepared silver nanoparticles in the matrix of bamboo cellulose nanocrystals were investigated for their ability to hasten the progress of healing events in streptozotocin induced diabetic mice model. Wounds treated with topically applied NCs (hydrogels) showed full recovery (98-100%) within 18days post wounding in contrast to the various control groups where incomplete healing (88-92%) was noticed.

Sustained delivery of BSA/HSA from biocompatible plant cellulose nanocrystals for in vitro cholesterol release from endothelial cells.

Nanocomposites of plant cellulose nanocrystals (CNCs) were developed by binding model proteins BSA and HSA onto CNCs by physical adsorption and chemical conjugation methods The spectroscopy and microscopy studies confirmed the protein binding onto CNCs. Phosphate buffer saline (pH=4.0, 7.

In situ functionalized nanobiocomposites dressings of bamboo cellulose nanocrystals and silver nanoparticles for accelerated wound healing.

An innovative approach was adopted where in situ synthesized silver nanoparticles (AgNPs) from leaf extract mediated reduction of AgNO were simultaneously impregnated into the matrix of cellulose nanocrystals (CNCs) isolated from Dendrocalamus hamiltonii and Bambusa bambos leaves, for formation of nanobiocomposites (NCs) in film and ointment forms. Here, use of plant CNCs was chosen as an alternate to bacterial cellulose for wound dressings. NCs possessing water absorption capacity and strong antibacterial activity showed synergistic effect on in vivo skin wound healing and documented faster and significant wound closure in treated mice.

Silver nanoparticles synthesised using plant extracts show strong antibacterial activity.

In this study, three plants Populus alba, Hibiscus arboreus and Lantana camara were explored for the synthesis of silver nanoparticles (SNPs). The effect of reaction temperature and leaf extract (LE) concentration of P. alba, H.

Nanoencapsulation for drug delivery.

Nanoencapsulation of drug/small molecules in nanocarriers (NCs) is a very promising approach for development of nanomedicine. Modern drug encapsulation methods allow efficient loading of drug molecules inside the NCs thereby reducing systemic toxicity associated with drugs. Targeting of NCs can enhance the accumulation of nanonencapsulated drug at the diseased site.
