Potential applications of nano LED in biomedical devices

The light emitting diode liquid inorganic nano crystal based (LED) because of the cheap and stable chemical properties and potential application in biomedical diagnosis, but because it is difficult to achieve the UV emission, the research has not made big breakthrough.

The day before, the Los Amos National Laboratory Sergio BrovELli research group and Italy Milan Alberto Paleari Bicocca university research group, developed a glass based inorganic semiconductor nanoparticles embedded in a LED. In this device, two tin oxide nanoparticles are wrapped in tin oxide and embedded in the glass material, the glass based material can emit light in the ultraviolet spectrum, and integrated into the chip. The electrical response of the whole material can be controlled by adjusting the thickness of the nanoparticles.

The device combines the chemical stability and mechanical stability of the glass, and has the properties of conductivity and electroluminescence. Therefore, it can be used in harsh environment (such as immersion in physiological solution or directly implanted into the human body), is expected to be used in the manufacture of biomedical equipment.
