Tailor-made nanomaterials for human benefit

International Conference on Nanomaterials and Nanochemistry
November 29-30, 2017 | Atlanta, USA

Keynote : Mater Sci Nanotechnol

Abstract:

Tailor-made nanomaterials designed for human benefit are going to be presented and discussed, such as, antiseptic fabrics loaded with nanosilver particles; hesperidin or nano-hesperidin loaded nanoparticles or formulations for anti-cancer and anti-aging therapies; and inert magnetic nanoparticles for sucrose removal. Many efforts to develop powerful antimicrobial agents or formulations that could be used in clinical treatments against pathogenic and resistant microorganisms have been made still, resistant pathogens are frequently present in hospital areas, complicating the treatment and cure of infections caused by them. In this respect, nanosilver particles show very interesting antimicrobial properties and have been applied in a wide range of products such as those for preventing hospital infections. These particles can be produced by chemical or biological methods. Our research is partly focused on bio-based synthesis of silver nanoparticles, their thorough characterization and application, for example, in cotton fibers impregnation that might be used in medical environment and clothing as to avoid microbial spreading. Nature keeps surprising us with incredible and simple solutions to many health problems. For example, hesperidin is an abundant citrus fruit flavanone that has many interesting properties regarding biological activity. These include anticancer prodrug effects against different cancer-cell lines and powerful antioxidant effects. Chemo protective roles in carcinogenesis and antioxidant activities of different formulations of hesperidin in some designed drug delivery systems are going to be presented. Finally, I shall finish this keynote lecture with tailored-made nanomagnets designed to benefit population that suffers from diabetes. As a chronical metabolic disease that leads to high glucose levels in the blood, diabetes has grave consequences to human health. Our research idea was to obtain a tailor-made nanomagnet, iron oxidebased, covered with an inert shell and enzyme-linked, as to capture and remove sucrose from a solution. These specially designed nanomagnets are stable, inert, easy to deal with, and reduce the time and cost of the process for obtaining low-sugar beverages.
