Nanotechnology Applications
Nanotechnology is science that involves working with matter at the molecular or nano-scale (25, 400, 000 nanometers equal 1 inch) dimension, the understanding and control of matter at dimensions between 1 and 100 nanometers (AmericanElements, 2010). Today where unique phenomena enable novel applications, this includes Fuel Cell Development, Biotechnology, and Medicine among others. Using the heating properties of iron oxide nanoparticles in gene regulation, cancer therapy, and temperature responsive valves has proven quite versatile over the years. In an interview for Nanowerk, Drs. Daunert and Markey of the Biochemistry and Molecular Biology Department of University of Miami discuss the use of a new nanocomposite hydrogel they have created, which is infused with dehalogenese enzymes and iron oxide nanoparticles that can be activated by remote activity (Knecht, 2012). Building on the knowledge that nanoparticles become heated when an alternating magnetic field (AMF) is present (Berger, 2012), they used the hydrogel nanocomposite in the AMF to find the ultimate enzyme action. They then heated the hydrogel in the conventional method, the water bath. What they found was that the new method (heating the nanocomposite hydrogel internally in the AMF) resulted in twice the increase of enzymic activity as the external heating in the conventional water bath. This suggests the system may be useful in the remote use of environmental and biomedically relevant enzymes in many fields (Knecht, 2012).

A company, Green Earth Nano Science, Inc. (GENS), headquartered in Toronto, Canada, is dedicated to, and specializes in the development and commercializing of sustainable “green” technology to protect homes and businesses against the spread of disease.

According to Nanotechnology Now, GENS was a finalist for the Green Log Award in 2008, which recognizes companies for their efforts in making the homes and communities healthier. GENS “Green 3D...
