Japan's Hokuriku University School of Advanced Science and Technology has announced that the school researchers have developed gold and silver nanoparticles, which can be used to produce high-sensitivity biosensors, to help doctors examine the patient's blood, urine, or genetic diagnosis.
glue stick The researchers first made ??a diameter of about 14 nanometers (a nanometer is a billionth of a meter) of gold nanoparticles and its surface coverage of about 4 nm thick silver film, and then on the silver film is then covered with a layer thickness of 0.1 nm gold, forming gold silver folder structure.glue gun The researchers observed the characteristics of this structure and found that it not only has a simple silver nanoparticles with the same sensitivity, but also has high chemical stability of gold properties, and easy integration with related molecules in vivo.
Associate Professor of the University led the research park before the letter also said: "If you use this nano-particles, bio-sensor performance will enable a leap increase, costs will be significantly reduced."
