Genetically Engineered Tattoo Shows Up if Person Has Cancer

As everyone knows, early diagnosis brings the best chance of fighting cancer. At ETH Zurich, a Swiss technical university, researchers genetically modified skin cells to produce a tattoo that makes itself visible only when the person wearing it has signs of cancer. The technology consists of a “synthetic gene network” that activates the (Read more...)

4Dx Uses Algorithms to Better Visualize Lung Function

Chronic obstructive pulmonary disease affects millions of people in the United States. The main method of diagnosis is the pulmonary function tests (PFTs), in which a patient breathes into a machine that measures pulmonary parameters. The disadvantage, however, is that pulmonary function tests take an “average” of a patient’s lung (Read more...)

Sugar-Coated Nanosheets Can Selectively Bind Pathogens

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have developed sugar-coated ultrathin self-assembling nanosheets that can selectively bind to pathogens, and which have potential to serve as a diagnostic technology or a way to inactivate pathogens. The researchers developed the structures using bioinspired (Read more...)

Partial Wave Spectroscopy Spots Cells Turning to Cancer

Detecting cancer in the body usually happens when the disease is already well underway to being mortally dangerous. Although there’s a myriad of cancers and ways to detect them, diagnostic tests typically look for biomarkers produced by tumors. And the bigger the tumor, the more biomarkers it releases, so the bigger it is the easier [… (Read more...)

Google’s Deep Learning Software Analyzes Retinal Images for Signs of Cardiovascular Risk

Google has been tinkering in the field of medicine over the last few years, including developing a prototype electronic contact lens. The company’s latest health project involves detecting cardiovascular conditions by analyzing the vasculature of the retina. The researchers built a deep learning system that processed data from two datasets co (Read more...)

Microfluidic Mixer Combines Fluids without Backflow to Make Advanced Portable Diagnostics Practical

Lab on a chip devices are designed to perform advanced diagnostics and drug testing using small samples of blood and other body fluids. We’ve written about many such devices, including for assessing the effectiveness of chemo and for picking out circulating tumor cells, but microfluidic technologies that rely on capillary or vacuum powered te (Read more...)

Soft, Transparent, and Comfortable Contact Lens Measures Glucose, Intraocular Pressure

A team of researchers in South Korea has developed a soft electronic contact lens capable of measuring glucose and intraocular pressure, a development that may help diabetes and glaucoma patients monitor their conditions. There have been previous attempts by ambitious companies and universities to do so in the past, but the results were not very [& (Read more...)

Biomeme’s Portable PCR System Expands Research Possibilities

Polymerase chain reaction (PCR) is one of the most widely used techniques in biological research and testing, allowing researchers to amplify and identify even small quantities of DNA or RNA. It serves a wide variety of uses, from genetic testing to infectious disease identification to forensics. Thermal cyclers, the machines that run PCR, are a [& (Read more...)
