Sensor Chip Screens Urine for Cancer Biomarker

Researchers from a multi-institutional group have developed a label-free chip-based sensor to detect very low levels of a cancer biomarker in urine. This exciting development may one day help catch cancer earlier, perhaps during regular screenings, leading to better outcomes. Current methods of cancer biomarker detection are often expensive and cha (Read more...)

DNA Circuits to Identify Cancer Cells

Researchers from Duke University have developed a new DNA-based tool to identify cancer cells. Their system is a DNA circuit. DNA binding to specific cell markers produces a signal if and only if two specific proteins are present, helping to improve specificity and reduce false positives in cancer cell detection. The researchers also hope that [&he (Read more...)

Tiny Medical Imaging Sensor Sets Guinness World Record

OmniVision Technologies, a Santa Clara, California firm, just announced that it has won the Guinness World Record for “The Smallest Commercially Available Image Sensor”. The OV6948 sensor was designed for use in catheters and endoscopes, allowing these devices to be as small as possible while also providing high quality imaging from wit (Read more...)

3D Liquid-Cell Electron Microscopy Imaging Now Possible

Electron microscopy revealed a world that exists at scales smaller than the wavelength of light. Advancements in this field have allowed scientists to visualize ever more objects and processes, but actually seeing living cells in 3D and within a liquid environment has been impossible. Now, a team of researchers from Penn State University, Virginia (Read more...)

3D Microenvironments to Grow Brain Tumors in Lab

Clinical researchers are constantly thwarted by the inability to quickly and easily try new therapies in tumors and other disease targets. Tumors within the brain are particularly hard to study because of the difficulty with access and the incredible fragility of nearby tissues. Researchers at Tufts University have just developed a way to create an (Read more...)

Red Light Activated Cancer Drug Improves Treatment in Mice

Researchers from the City University of Hong Kong have developed a new, controllable cancer drug called phorbiplatin that only becomes active and potent after red light stimulation. Their work demonstrates that in the dark the cancer drug does not have substantial toxicity, but the drug is able to substantially reduce tumor size when activated by [ (Read more...)

New Imaging Technique Reveals Deep Tumors, Helps Attack Them

Tumors deep inside the body can be very difficult to spot, track, and study. The brain, being surrounded by a thick skull, is particularly challenging to image using light, so MRI and CT are currently the go-to imaging modalities when looking at deeply seated tissues. Now, researchers at Stanford University are reporting the development of [&hellip (Read more...)

New Chip for Microwave Imaging of Body

Today’s clinicians are limited to a few imaging modalities, primarily X-ray, CT, MRI, and ultrasound. Microwaves, in principle, can also be used as a useful way to look inside the body. Microwave radiation is non-ionizing, so should be safer than X-rays, but in practice microwave imagers, because of the electronics inside, have remained bulky (Read more...)
