Water-Templated, Polysaccharide-rich Bioartificial 3D Microarchitectures as Extra-Cellular Matrix Bioautomatons.

This is the first report of exploiting the "quasi-spherical" shape of water molecules for recapitulating a true human extracellular matrix (ECM). Herein, water behaved as a quasi-spherical porogen, for engineering polysaccharide-rich and chemically defined 3D-microarchitecture, with semi-interpenetrating networks (S-IPNs). Furthermore, their viscoelastic behavior along with a heterogeneous, fibroporous morphology, facilitated instructive, self-remodeling of the bioartificial scaffolds, thence effectively permitting and promoting the growth of 3D tumor spheroids of divergent origins.

Electrochemically synthesized highly crystalline nitrogen doped graphene nanosheets with exceptional biocompatibility.

This work reports first electrochemical preparation of exceptionally biocompatible, highly crystalline, and well exfoliated nitrogen doped graphene nanosheets (eNGS) from carbon nanosheets for the development of mighty platforms in the field of modern biosensing and other biological applications for human welfare. eNGS displayed exceptional biocompatibility. Administration of the as-synthesized eNGS to rat models did not lead to any significant deviation or inimical consequences in its functional observation battery (FOB) tests, GSH levels or the histology of the vital organs of the rat models.

Therapeutic Implications of Superoxide Dismutase And Its Importance in Kinase Drug Discovery.

In recent years, several scientific investigations have reported the therapeutic implications of superoxide dismutase (SOD) against oxidative stress and -induced pathology in clinical and preclinical trials. Indeed, various kinase, molecular signaling and physiological process has altered by reactive oxygen species. In spite of the abundant available literature reports, patents, clinical trials and commercialized products, the therapeutic application of SOD as a potential drug still remains unclear.

Hydrothermally functionalized biocompatible nitrogen doped graphene nanosheet based biomimetic platforms for nitric oxide detection.

Hydrothermal synthesis of nanocomposites is of significant importance, as it affords facile, biocompatible, nontoxic, and economic fabrication. Herein, we report a hitherto unexplored cytocompatible and reusable biomimetic electrochemical sensor based on pyridyl porphyrin functionalized nitrogen doped graphene nanosheets. The porphyrin functionalized nitrogen doped graphene nanosheets (PFNGS) were prepared by a low temperature hydrothermal method via non-covalent strategies with a minimal impact on their physicochemical properties.
