Nano and Biomaterials

Nanotechnology is shaping the practice of medicine, promising advances of unprecedented scope. 

It is highly likely that many chronic diseases now considered incurable — including several types of cancer — will ultimately yield to molecular medicine. Innovative diagnostic procedures will allow physicians to detect anomalies at the cellular level, greatly enhancing the likelihood of desirable treatment outcomes.  New nanomaterials and biomaterials ultimately will result in sophisticated prosthetic devices, even synthetic or bioengineered organs. The Department of Materials Science and Engineering is working with allied departments to accelerate the development and deployment of these materials.

Stanford engineers have created a nanoscale probe they can implant in a cell wall without damaging the wall. The probe could allow researchers to listen in on electrical signals within the cell. That could lead to a better understanding of how cells communicate or how a cell responds to medication. The probe could also provide a better way of attaching neural prosthetics and with modification, might be an avenue for inserting medication inside a cell.

Researchers think blood proteins may hold key to developing instruments for use by first-responders, labs in the event of nuclear incidents.

Improved magnetic-nano sensor chips are up to 1,000 times more sensitive than current methods of cancer detection — and can scan any bodily fluid with high accuracy and search for up to 64 cancer-associated proteins simultaneously.

Among its many talents, silver is an antibiotic. Titanium dioxide is known to glom on to certain heavy metals and pollutants. Other materials do the same for salt. In recent years, environmental engineers have sought to disinfect, depollute, and desalinate contaminated water using nanoscale particles of these active materials. Engineers call them nanoscavengers. The hitch from a technical standpoint is that it is nearly impossible to reclaim the nanoscavengers once in the water.

The Department of Energy has awarded Professor Reinhold Dauskardt $1.165 million to study how factors such as heat fluctuations and moisture changes will affect the photovoltaic arrays that utility companies would use to build large scale solar power plants.

"Predicting the lifespan of new technologies is vital to their widespread adoption," said Dauskardt, the Ruth G. and William K. Bowes Professor in the School of Engineering. "You have to be confident that your investment will pay off."

It is a turbulent and sometimes deadly life for cells injected to heal injuries. The act of being squirted through a thin needle into the site of an injury jostles the delicate cells against each other and against the needle walls. Then, once in the site of injury, they face a biological war zone of chemicals. It's no wonder, then, that treating spinal cord injuries and other damage with injected cells has been a challenge.
