Tumor spotting, tracking, and studying are challenging tasks in the cases when a thick layer of exoskeleton and muscles covers cancer. Light-based imaging techniques fail to spot cancer. Therefore, clinicians have been using CT and MRI modalities to visualize the entrenched tumorous tissues.Recently, scientists at Stanford University have come up with a new approach of illuminating the tumorous cells residing underneath the skin.The team has designed new nanoparticles for thisapproach. Besides tumor diagnosis and monitoring, the nanoparticles are also capable of predicting the response of a patient against specific immunotherapy.
The researchers opted for erbium—a rare-earth element—for creating nanoparticles, as erbium glows when exposed to the infrared. The team coated those nanoparticles with a unique layerwhere cancer-specific antibodies can adhere. Moreover, the layer lessens the nanoparticles’ toxicity, allowing them to disperse easily in the bloodstream.The nanoparticles carrying cancer-specific antibodies on their surfaces spread across the body through the bloodstream. In case, the specific tumor cells are settled inside the body, the targeted antibodies attach to those cells. After the antibodies' delivery, the researchers exposed the body to low energy light, illuminate the specific tumor cells residing in any part of the body.
To demonstrate their novel approach, the Stanford researchers conducted the lab trials on a mouse. Initially, the team induced tumors inside the mice's brains and then exploited the glowing nanoparticles approach to diagnose and monitorthe particular cancer cells under infrared exposure.On a related note, researchers from aCalifornia-based biotechnology company, Grail, have developed a new blood test that is capable of screeningover twenty types of cancers with great precision. The company probes DNA using next-generation sequencing to examine which part of the genome is active.With this approach, the researchers can fetch cancer signals from the blood samples extracted from cancer patients.
