In India and Southeast Asia, turmeric has long been used as a treatment for inflammation, skin wounds and tumors. Curcumin has broad spectrum cancer chemo preventive activity in preclinical animal models. The anticancer potential of curcumin stems from its ability to suppress proliferation of a wide variety of tumor cells, downregulatetranscription factors NF-κB, AP-1 and Egr-1; down-regulate the expression of COX2, LOX, NOS, MMP-9, uPA, TNF, chemokines, cell surface adhesion molecules and cyclin D1; down-regulate growth factor receptors (such as EGFR and HER2); and inhibit the activity of c-Jun N-terminal kinase, protein tyrosine kinases and protein serine/threonine kinases. In several systems, curcumin has been described as a potent antioxidant and anti-inflammatory agent. Evi...

The SRGO has been prepared using naturally available solar light for the reduction of graphene oxide. Various material characterization techniques have recognized SRGO for its morphology and conductivity. A detailed electrochemical study has been performed to test the applicability of SRGO for ascorbic acid sensing. SRGO modified electrode shows a quick response time (~2s) and ascorbic acid was detected over a narrow linear range of 20µM to 360 µM. The developed sensor also shows a high sensitivity of 114 µAmmol-1cm-2 and a lower limit of detection 56 (µM) for the ascorbic acid sensor. These results indicate that SRGO could be applied for the electrochemical study of vitamin C in food and vegetable samples.

In present paper we report that present method highly selective, simple, efficient, accurate, ecofriendly, less toxic. The prepared composite were characterized by material characterization like SEM, XRD and also by electrochemical characterization like CV, chronoamperometry represents that copper oxide-graphene shows excellent electrocatalytic activity towards glucose, exhibiting a good sensitivity of 103.84 µA mM−1 cm−2, a fast response time 2s, a low detection limit 0.00033µM and linear range from 10 µM-3000 µM. The present sensor can successfully apply for determination of glucose concentration in human blood sample.
