A new approach to the identification of harmful bacteria: A new study explores how spectroscopic techniques can be used for quick analysis directly from the skin.
Researchers from the University of Birmingham have designed and developed a novel diagnostic device to detect traumatic brain injury (TBI) by shining a safe laser into the eye.
Researchers have developed a Raman microscope that can acquire information hundreds of times faster than the conventional method. This could help expand its usefulness in biomedical applications.
Researchers created a special ultrathin sensor, spun from gold, that can be attached directly to the skin without irritation or discomfort. The sensor can measure different biomarkers or substances to perform on-body chemical analysis.
Researchers have developed a noninvasive and reagent-free technique for the efficient detection of COVID-19.
Handheld laser devices that help surgeons quickly spot liver damage could transform transplant procedures, research suggests. The non-invasive technique could provide medical staff with instant data on the health of donor livers and help them to identify which organs are suitable for transplant. If widely adopted, the light-based tool could allow more livers to be transplanted safely and…
Improving the detection of cancerous cells during surgery – this is the goal of the European research project CARMEN. The research institutes Laser Zentrum Hannover e.V. (LZH) from Germany and Multitel asbl from Belgium work together with companies from both countries, JenLab GmbH, Deltatec, and LaserSpec, to develop a novel, compact and multimodal imaging system. This could even allow the…
Researchers have created better biosensor technology that may help lead to safe stem cell therapies for treating Alzheimer’s and Parkinson’s diseases and other neurological disorders.
More and more people aged 50 and over are suffering from age-related vision disorders. According to the World Health Organization, in four out of five cases they could be avoided if they were diagnosed at an early stage. A European team of scientists, including the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, has now researched a new method that will enable doctors to better…
Analytically sensitive and specific detection of pharmaceuticals or metabolites in bodily fluids, as well as fast and reliable detection of human pathogens, are major challenges for instrument-based analytics in medical diagnostics. Over the past few years the combination of surface-enhanced Raman spectroscopy (SERS) and microfluidic devices (Lab-on-a-Chip) has emerged as a perfectly suited…
Researchers recently evaluated the accuracy of a technology to monitor blood glucose levels without needles or a finger prick. Early results show that the noninvasive technology measures blood glucose levels as effectively as a finger prick test — without drawing blood.
Recognising malignant tissue remains a tricky task. While today, most patients undergo a biopsy, an invasive procedure where tissue is sampled, stained and assessed, researchers are exploring the potential of optical biopsy, the visual assessment of suspect tissue. The interest in optical biopsy ‘is indeed enormous,’ confirms Dr Thomas Bocklitz, physicist at Friedrich-Schiller University in…
Canadian researchers have invented an intraoperative probe that reliably detects multiple types of tumour cells.
A team of Stanford University School of Medicine researchers has developed a new type of imaging system that can illuminate tumors in living subjects-getting pictures with a precision of nearly one-trillionth of a meter.
