Title of presentation: From silk at the nanoscale for osteochondral regeneration to bio-based multifunctional carbon nanoparticle for anticancer drug delivery
We are often confronted with numerous maladies and medical issues in all walks of our lives. Amongst others, the issue of degenerating osteochondral interface irks millions globally. In the first phase of the presentation, I shall try to highlight the prospects of a hybrid nanofibrous biomimetic scaffold (with an elastic region relevant for cartilage tissue and a stiff compression resistant region simulating the bone phase) based on the sustainable bio-resource, silkworm silk fibroin (mulberry Bombyx mori and endemic Indian non-mulberry Antheraea assamensis) and sol derived 70S bioactive glass to address the structure-function complexity at the osteochondral interface, evinced via various in vitro biological assessments pertaining to expression of specific marker genes, enzyme activity and matrix protein deposition, pertinent for osteochondral tissue repair. In the second part of the talk, I shall focus on the green-chemistry (microwave-assisted) mediated preparation-protocol, characterization and prospects of yogurt-drink (lassi) based multi-functional biocompatible, photoluminescent carbon nanoparticles as effective ferry for targeted delivery of an anticancer drug with highlights on plausible mode and nature of bio-nano interfacial action.
