New flexible, transparent, wearable biopatch, improves cellular observation, drug delivery

Minimally invasive patch delivers exact doses directly into cells, lessens pain, toxicity

12-Nov-2018 - Purdue University researchers have developed a new flexible and translucent base for silicon nanoneedle patches to deliver exact doses of biomolecules directly into cells and expand observational opportunities."This means that eight or nine silicon nanoneedles can be injected into a single cell ...

Beer. Soup. Barley's next great use? A medical imaging drink

28-Jun-2018 - Before launching their latest science experiment, University at Buffalo researchers bought more than 200 types of tea, chocolate, herbs and other foodstuffs. The goal wasn't to stock up for long hours in the lab, but rather to find an elusive, edible contrast agent to show doctors what's ...

Automated robotic device for faster blood testing developed

14-Jun-2018 - Rutgers researchers have created an automated blood drawing and testing device that provides rapid results, potentially improving the workflow in hospitals and other health-related institutions to allow health care practitioners to spend more time treating patients. "This device represents the ...

How signals get inside cancer cells and spur aggressive growth

15-May-2018 - The outside of a cancer cell is bombarded by signals. They come from the immune system, supporting tissues and other structures. But how do those signals impact cancer? A new study provides a surprising model of the process by which those signals enter and influence the cell. The finding could ...

GLUT5 fluorescent probe fingerprints cancer cells

23-Apr-2018 - Determining the presence of cancer, as well as its type and malignancy, is a stressful process for patients that can take up to two weeks to get a diagnosis. With a new bit of technology--a sugar-transporting biosensor--researchers at Michigan Technological University hope to reduce that ...

Self-powered paper-based 'SPEDs' may lead to new medical-diagnostic tools

25-Aug-2017 - A new medical-diagnostic device made out of paper detects biomarkers and identifies diseases by performing electrochemical analyses - powered only by the user's touch - and reads out the color-coded test results, making it easy for non-experts to understand. "You could consider this a portable ...

Seeing DNA 'blink'

21-Feb-2017 - Many of the secrets of cancer and other diseases lie in the cell's nucleus. But getting way down to that level -- to see and investigate the important genetic material housed there -- requires creative thinking and extremely powerful imaging techniques. Vadim Backman and Hao Zhang, nanoscale ...

New method to detect ultrasound with light

15-Feb-2017 - A tiny, transparent device that can fit into a contact lens has a bright future, potentially helping a range of scientific endeavors from biomedicine to geology. Developed by Northwestern University scientists, the device, called the Micro-ring resonator detector, can determine the speed of the ...

Detecting early onset of metastatic disease using FAST disc

09-Feb-2017 - The key finding of this study is the development of a new technique that seperates circulating tumor cells (CTCs) from whole blood at a liquid-liquid interface. In the study, UNIST Professor Yoon-Kyoung Cho, one of the group leaders at IBS Research Center for Soft and Living Matter (CSLM), ...

World's first total-body PET scanner takes a big step forward

19-Jan-2017 - The UC Davis-based EXPLORER consortium, which aims to build a revolutionary total-body PET (positron emission tomography) scanner, has announced the selection of two industry partners to help build the prototype device. They are United Imaging Healthcare America, a North American subsidiary of ...
