Blog Post 8: Applications

Blog Post 8: Applications
Find 10 nano-applications of interest to you. Post a brief description and a link for more info. For each application, explain the "nano" part based on the descriptions of what makes nano special from the nano.gov website: http://www.nano.gov/nanotech-101/special

This article reviews the limitation of drug deployment in sensitive areas like the eyes. Usual drugs are administered via topical solutions suspenstions and ointment. It also describes other theoretical ways to administer treatment at a nanometer scale. Techniques like microemulsions, nanosuspensions, nanoparticles, liposomes can be used to advance the field of ocular drug delivery.

While nanotechnology has large potential there needs to be improvements because miniscule devices will need a powersource better than a battery. Wasted energy or the human pulse could provide devices the energy to run simple gadgets. Piezoelectric nanowires could also be used to power medical devices like a pacemaker or an implantable wireless blood glucose meter.

The increasing need to have precise control over semiconductor, optical, electrical and mechanical devices creates a bottleneck at the increasing difficulty to machine materials such as ceramics, glasses and silicon wafers at such a scale. This paper they use a multi wall carbon nano tube in the machining process to increase accuracy and efficiency.
