Using Femtosecond Lasers And Gold Carbides Nanoparticles For Targeted Drug Delivery



Hongwu International Group Ltd, with HWNANO brand, is a high-tech enterprise focusing on manufacturing, research, development and processing of nanoparticles,nanopowders, micron powders. 

A joint team of researchers from Japan’s Okinawa Institute of Science and Technology (OIST) and the University of Otago, New Zealand has developed a new method for administering drugs to highly specific target sites using a combination of laser technology, Carbides Nanoparticles, and neuroscience.

“With this method, we can administer a wide range of drugs with precise timing and duration using laser pulses with sub-second accuracy,” Takashi Nakano, a member of the research team who works in the OIST Neurobiology Research Unit, said in a press release published recently on OIST’s website. “We are very excited about the potential this new tool brings to neurobiological research.”

In a recent study, the results of which have been published in the journal Scientific Reports, researchers tested their new technique as a possible treatment method for Parkinson’s disease.

Because Parkinson’s Disease disrupts the body’s release of the neurochemical dopamine, researchers wanted to use their technique to manually simulate and restore this natural process. They began by encapsulating dopamine inside a shell of fat, called a liposome, which was then tethered to a gold nanoparticle. When a pulsating femtosecond laser hit the gold, the nanoparticle transferred the energy into the liposome, causing it to open and release the encased dopamine..
