Taiwan Presents Gold-diamond Nanodevice for Hyperlocalized Cancer Therapy

Precise targeting of cancer cells, or generally biological molecules, for treatment is a challenge, due to their sheer size. Now, scientists from Taiwan have developed an advanced solution that can potentially be applied to thermal cancer therapy.

According to scientists, the advanced solution is based on a novel combination of previously used techniques.

Pei-Chang Tsai from the Institute of Atomic and Molecular Sciences, at the Academia Sinica, Taipei, Taiwan, and his research team published the improved sensing technique for nanometre-scale heating and temperature sensing in EPJ Quantum Technology.

Researchers have developed a variety of nanoparticles. These particles can be made to heat up when excited by an external energy source.

A gold nanoparticles with built-in diamond nanocrystal thermometers that can report their temperature when excited. While the gold nanorods heat up in response to a laser light, the fluorescent nanodiamonds glow due to the increased temperature.

A light detector can be used to spot the illumination coming from the nanodiamonds, together with the nanoparticles resulting in a thermometer for thermal nanoparticles.
