2009 Lemelson-Rensselaer Winner Developed Carrier For Nanoparticles

Yuehua Yu, nicknamed "Tony," arrived at Rensselaer Polytechnical Institute (RPI) in 2004 with a degree in chemistry and an advanced degree in polymer science from Nankai University in China. Today he received the Lemelson-Rensselaer Student Prize of $30,000 for his advancement in the fields of medicine, energy production and storage, water purification, electronics, and many other fields that work with nanoparticles.

Yu solved a major problem relating to the transport of nanoparticles from one place to another. Many liquids had been tried; however, nanoparticles seem to either clump together in the liquids or disperse so thoroughly that they become ineffective. Yu studied the effects of guanosine or "G-gels." He developed the first G-gel that was comprised of more than one guanosine compound, a binary G-gel, that is liquid at low temperatures, but when heated to body temperature, becomes gel-like.

It turned out that variations from liquid to gel in the G-gels were relatively easy to adjust by fine-tuning temperature. This meant that G-gels were an ideal carrier, not only for nanoparticles, but for live cells and enzymes that may be needed as therapeutic solutions to insert into the body.

G-gels can also act as a preservative and a restorative for enzymes. Perhaps one day, enzymes inserted into the skin with G-gel may be the ultimate non-surgical face-lift?

More importantly, Mr. Yu's discoveries will be well received in medical laboratories, as well as by doctors and patients, once nano-medicines become widely used therapy for major illnesses and disorders. Thank you, Tony! And congratulations!

Fail sticker for your spelling....

As an RPI alum, I thought the article was nice and I'm proud for "Tony."

However, you get a "FAIL" sticker for misspelling Rensselaer in the body of the article right after you spelled it correctly in the title.

RPI alums

I corrected the misspelled word in the text of the article, which was so graciously pointed out by "anonymous" Rensselaer alum above. Having two RPI alums and one entering RPI student in my family, I know that the correct spelling of Rensselaer is very important.
