Paper sensors for timely detection of cancer developed by Sangeeta Bhatia and her team

Sangeeta Bhatia is a biomedical engineer best known for developing new technologies for cancer diagnosis and treatment.

Boston: Experts at the Massachusetts Institute of Technology (MIT) have spread advanced nanoparticles on paper to create a cancer detection sensor.

By putting a few drops of urine on this simple and inexpensive sensor, it is possible to determine whether or not the patient has cancer. Nanoparticles target cancer-causing proteins specifically. Different types of tumors can thus be understood, and better treatment methods can be devised.

It is simply applied to a paper strip with nanoparticles. When small pieces of protein-DNA in urine collide with nanoparticles, they separate to form a DNA barcode. This demonstrates the presence of cancerous DNA in the urine and also indicates the type of cancer.

Sangeeta Bhatia and her team created it. It was tested on mice, and the paper test also identified five enzymes secreted by cancerous tumors, which is a significant step forward. The findings of this study have been published in the journal Nature Nanotechnology.

Sangeeta Bhatia is a biomedical engineer best known for developing new technologies for cancer diagnosis and treatment. She is an electrical engineering and computer science professor at MIT, as well as a member of the Whitehead Institute for Biological Research. Bhatia’s team created the paper sensor using a technique known as paper-based microfluidics. 

Microfluidics is a technology that controls the flow of fluids through tiny channels. The microfluidic channels in the paper sensor are used to transport blood samples to the areas where cancer biomarkers are detected.
