Honolulu, HI (PRWEB) October 18, 2006
Professor Zhanfang Ma from the Chemistry Department at Northeast Normal University in Chanchun, PR China, explains his group's recent findings to Nanowerk; "Amino acid molecules are one of the most important candidates to fabricate nanomaterials due to their stability, cost-saving, nontoxicity, and biocompatibility. Herein, we prepared multiple shapes of nano- and micro-structured cystine aggregates only by adjusting the concentration and pH value of the L-Cysteine solution under ultrasonic irradiation."
Importantly, as Ma points out, a large amount of highly monodispersed nanospheres of cystine aggregates 225 nm in diameter without any other shapes were easily obtained.
"To the best of our knowledge, this is the first time highly monodispersed nanospheres have been prepared using a common amino acid with small molecular weight" he says. "The reported method will promote new possibilities for future applications in biosensor, drug delivery, and medicine."
The new findings were reported in a paper, titled "A facile method to produce highly monodispersed nanospheres of cystine aggregates", published in the September 28, 2006 online edition of Nanotechnology.
