Abstract
Nanobiotechnology is an exuberant sphere of science that exhibits potential application in cancer therapy, targeted chemotherapy, molecular diagnosis and molecular imaging. Present investigation discloses green route synthesis of selenium nanoparticles leading to functionalization as anti leukemia nanomaterial. Emergence of resistance over cancer radiotherapy and chemotherapy is found to be the key factor behind the clinical treatment failure and recurrence. Selenium nanoparticles (SeNPs) with distinctive physicochemical features emerged as a novel nanocarrier and therapeutic agent with broad spectrum of medicinal properties. On the basis, biogenic technology has been proposed to synthesize selenium nanoparticles using Cassia auriculata and characterized using standard techniques. Newly synthesized selenium nanoparticles’ UV intense peak is achieved at 252 nm with crytalline surface morphology clear in SEM analysis. Cassia auriculata mediated selenium nanoparticles’ TEM analysis exhibits polydispersed with 10–20 nm. FTIR spectrum confirms the reduction of carboxyl group and capping of alkane group in Cassia auriculata synthesizes the selenium nanoparticles and its anti cancer potentiality has been explored by anti-leukemia activity using in vitro studies.
