by Brigham Young University The COVID-19 pandemic has posed a serious issue for doctors and nurses assessing a patient’s heart and lungs with a traditional stethoscope. Many healthcare practitioners have found it difficult to position the stethoscope correctly around their face masks. These assessments also require practitioners to be very close to the patient, heightening...
by University of Sheffield New dressings that could be used to treat diabetic wounds and burns injuries more effectively have been developed by engineers from the University of Sheffield The cotton-based dressings, developed by Professor Sheila MacNeil from the University’s Department of Materials Science and Engineering, release an agent that promotes the formation of new...
by Beckman Institute for Advanced Science and Technology Researchers at the GSK Center for Optical Molecular Imaging have developed a new microscope that looks at the different parameters that change during wound healing. They hope to use this technique to understand how skin disorders, such as foot ulcers in diabetic patients and psoriasis, can be...
Innovative wireless split-ring resonator concentrates microwaves into a hot-spot for ultrasound emission SPIE–INTERNATIONAL SOCIETY FOR OPTICS AND PHOTONICS Ultrasound imaging is one of the workhorses in a modern hospital. It hits the trifecta of being relatively cheap, portable, and non-invasive. The ability to cause future parents to get a bit emotional over fetus images is...
WEST LAFAYETTE, Ind. – Conventional melanoma therapies, including chemotherapy and radiotherapy, suffer from the toxicity and side effects of repeated treatments due to the aggressive and recurrent nature of melanoma cells. Less invasive topical chemotherapies have emerged as alternatives, but their widespread uses have been hindered by both the painful size of the microneedles and...
Being able to tell, in a matter of seconds, whether someone is infected with the virus that causes COVID-19 would certainly help put a halt to the ongoing pandemic. Existing tests typically involve a deep nasal swab to obtain enough fluid sample, which has to be transferred to a laboratory machine for processing, with the...
by Dennis Thompson, Healthday Reporter A cutting-edge “lab-on-a-chip” has shown promise in detecting early breast cancers and tumors that have developed in other parts of the body. Roughly the size of a glass microscope slide, the EV-CLUE uses nanotechnology to pump a tiny amount of blood into eight miniscule channels equipped to detect different markers...
he team created an eye scanner that can tell someone’s ‘real’ or biological age There is no universal method for tracking a person’s biological age, authors say By building this new scanner they were able to create one method to see the age The team say that biological age is a more accurate health measure...
by Rice University A sample of Rice University’s ‘magnetoelectric’ film atop a bed of uncooked rice. Rice neuroengineers created the bi-layered film to power implantable neural stimulators that are approximately the size of a grain of rice. The film converts energy from a magnetic field directly into an electrical voltage, eliminating the need for a...
Precise delivery of therapeutic drugs into diseased tissue remains a challenge in a variety of cases. Tumors can be hard to seed with chemo agents, particularly when the blood flow is not favorable for delivery. Now, researchers at the Max Planck Institute for Intelligent Systems in Germany have developed microscopic drug delivery devices that can...
