A wearable device that alerts people with food allergies before a reaction begins has the potential to reduce life-threatening anaphylaxis and transform allergy management from reactive to preventive care. The AllergE patch is a microneedle-based biosensor developed by researchers at KAUST that painlessly detects immunoglobulin E (IgE), the antibody that triggers allergic reactions, directly from the fluid beneath the skin. https://medicalxpress.com/news/2026-03-smart-patch-allergies-symptoms.html Mon, 02 Mar 2026 16:20:05 EST news691686915 The human brain is complex. Understanding deep brain function usually requires the insertion of probes that frequently result in irreversible tissue damage. Current neural probes are made out of silicon, a brittle material that can shatter during placement. https://medicalxpress.com/news/2026-01-customizable-stainless-steel-neural-probes.html Wed, 14 Jan 2026 15:59:37 EST news687628741 How do the circuits of the human brain work—and what happens when they are disrupted? To investigate these questions, researchers at the Eye Clinic of the University Hospital Bonn (UKB) and the University of Bonn, together with colleagues from the University of Münster and Harvard Medical School, have developed an innovative platform that allows the function of neural networks to be studied in a targeted manner. The results have now been published in the journal ACS Nano. https://medicalxpress.com/news/2025-10-platform-enables-precise-production-human.html Tue, 28 Oct 2025 12:13:42 EDT news680872419 Circulating tumor cells (CTCs) refer to cancer cells that have broken off from a primary tumor. These tumor cells can travel through the blood in the circulatory system and lodge themselves in other organs to cause secondary tumors. Therefore, the detection and subsequent characterization of CTCs from blood can help in the clinical diagnosis and treatment of various cancers. However, the efficient capture of CTCs from blood has been proven to be difficult. https://medicalxpress.com/news/2025-07-cancer-cells-blood-microfluidic-device.html Tue, 29 Jul 2025 11:43:14 EDT news673008182 In the future, delivering therapeutic drugs exactly where they are needed within the body could be the task of miniature robots. Not little metal humanoids or even bio-mimicking robots; think instead of tiny bubble-like spheres. https://medicalxpress.com/news/2024-12-tiny-robots-tumors-precision-drug.html Wed, 11 Dec 2024 14:00:01 EST news653132761 Organs-on-chips (OoCs) represent a revolutionary advancement in the study of human physiology and disease, offering an in vitro microphysiological environment that mimics the functions of human organs. These devices combine cell biology and engineering to create a platform that supports the growth and function of cells outside the human body. A comprehensive review, published in the Journal of Exploratory Research in Pharmacology, explores the current state of OoC technology, its applications, challenges, and future prospects in drug development, disease modeling, and personalized medicine. https://medicalxpress.com/news/2024-07-chips-insights-molecular-mechanisms-disease.html Mon, 22 Jul 2024 13:09:28 EDT news640872564 During synthetic scaffold implantation in a clinical setting, graft-host mechanical mismatch is a long-standing issue for soft tissue regeneration. While bioengineers have denoted numerous efforts to resolve this challenge, the regenerative performance of the synthetic scaffolds can be limited by slow tissue growth conditions when compared to autografts, alongside mechanical defects. https://medicalxpress.com/news/2023-10-bioinspired-flexible-network-scaffolds-soft.html Wed, 04 Oct 2023 09:56:39 EDT news615632190 A team of engineers at the University of California San Diego has developed a stretchable ultrasonic array capable of serial, non-invasive, three-dimensional imaging of tissues as deep as four centimeters below the surface of human skin, at a spatial resolution of 0.5 millimeters. This new method provides a non-invasive, longer-term alternative to current methods, with improved penetration depth. https://medicalxpress.com/news/2023-05-wearable-ultrasound-patch-non-invasive-deep.html Wed, 03 May 2023 10:27:01 EDT news602328416 Missing crucial doses of medicines and vaccines could become a thing of the past thanks to Rice University bioengineers' next-level technology for making time-released drugs. https://medicalxpress.com/news/2023-04-21st-century-remedy-meds-time-released-drugs.html Mon, 03 Apr 2023 12:53:00 EDT news599745175 Engineering researchers have invented an advanced brain-computer interface with a flexible and moldable backing and penetrating microneedles. Adding a flexible backing to this kind of brain-computer interface allows the device to more evenly conform to the brain's complex curved surface and to more uniformly distribute the microneedles that pierce the cortex. The microneedles, which are 10 times thinner than the human hair, protrude from the flexible backing, penetrate the surface of the brain tissue without piercing surface venules, and record signals from nearby nerve cells evenly across a wide area of the cortex. https://medicalxpress.com/news/2022-03-brain-computer-interface-flexible.html Tue, 15 Mar 2022 10:37:32 EDT news566559448 Across the world, several million people every year suffer from spinal cord injury. These types of injuries break the communication links between the brain and body, reducing movement and sensation, and in the worst cases, can lead to paralysis. https://medicalxpress.com/news/2021-11-scaffold-growth-regenerating-neurons.html Mon, 29 Nov 2021 10:55:30 EST news557405721 When it comes to cancer detection, size matters. Traditional diagnostic imaging cannot detect tumors smaller than a certain size, causing missed opportunities for early detection and treatment. Circulating tumor exosomes are especially small cancer biomarkers and easy to miss. These nanovesicles are composed of molecules that reflect the parental cells. But, because they are tiny (~30-150nm in diameter) and complex, the precise detection of exosome-carried biomarkers with molecular specificity is elusive. https://medicalxpress.com/news/2021-10-advance-rapid-cancer.html Mon, 11 Oct 2021 16:51:03 EDT news553189860 An international research team led by Monash University has uncovered a new technique that could speed up recovery from bone replacements by altering the shape and nucleus of individual stem cells. https://medicalxpress.com/news/2021-04-pillar-breakthrough-discovery-bone-implant.html Fri, 09 Apr 2021 10:20:40 EDT news537182437 A recent innovation from an EPFL laboratory will enable, for the first time, mass production of standardized organoids. This breakthrough was achieved thanks to a customized guidance system that ensures homogenous cell culturing. Described in an article published today in Nature Biomedical Engineering, the technique paves the way for industrial uses, such as screening new drugs. https://medicalxpress.com/news/2020-06-standardizing-organoid-growth-guidance.html Mon, 08 Jun 2020 09:49:01 EDT news510828535 In the quest to engineer replacement tissues and organs for improving human health, biofabrication has emerged as a crucial set of technologies that enable the control of precise architecture and organization. A new article reviews the impacts of biofabrication in tissue engineering and regenerative medicine over the previous year. The article is reported in Tissue Engineering, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. https://medicalxpress.com/news/2020-04-biofabrication-tissue.html Wed, 29 Apr 2020 12:06:18 EDT news507380776 Like DNA, ribonucleic acid (RNA) is a type of polymeric biomolecule essential for life, playing important roles in gene processing. Short lengths of RNA called microRNA are more stable than longer RNA chains, and are found in common bodily fluids. The level of microRNA in bodily fluids is strongly correlated with the presence and advance of cancer. This means that microRNA can act as an easily accessible biomarker to diagnose cancer, which causes over 14% of deaths annually worldwide. https://medicalxpress.com/news/2017-03-ultrafast-cancer-biomarker-enabled-nanobiodevice.html Wed, 08 Mar 2017 10:10:01 EST news408186653
