Nano-chips detect cancer early in humans

Researchers at Stanford University are developing highly sensitive nano-sized chips that can detect early biomarkers that show cancer in humans.

According to the researchers, the chip is about 1,000 times more sensitive than current technology and can detect biological signatures at three times lower density than current methods.

The early detection of biomarkers is very useful as it will increase the survival rate of patients with cancer.

"In the early stages of cancer, the level of protein in the bloodstream is very low, so there needs to be a super-sensitive technology ," says Shan Wang, author of the paper. detect it '.

According to Wang, the nanoparticle can determine the biological signaling protein at a density of only one hundred billion (or 30 molecules per 1 mm ³ blood) and also allow physicians to quickly determine the response. of patients receiving chemotherapy regimens.

"We can now determine whether the treatment is effective for 2-3 days, instead of 1-2 months," he said.

The nanoparticles have shown efficacy in detecting tumors in mice and can identify 64 different proteins. The researchers also hope it can detect other diseases.
