Imagine a swarm of tiny devices only a few hundred nanometers in size that can detect trace amounts of toxins in a water supply or the very earliest signs of cancer in the blood. Now imagine that these tiny sensors can reset themselves, allowing for repeated use over time inside a body of water – or a human body.
An NJIT research professor known for his cutting-edge work with carbon nanotubes is overseeing the manufacture of a prototype lab-on-a-chip that would someday enable a physician to detect disease or virus from just one drop of liquid, including blood.
A new study reports that the use of a quarterly report card is associated with improved colonoscopy quality indicators. Endoscopists at the Roudebush Veterans Affairs Medical Center in Indianapolis, Ind., who participated in the study showed an overall adjusted adenoma (precancerous polyp) detection rate increase from 44.7 percent to 53.9 percent, and a cecal intubation rate increase from 95.6 percent to 98.1 percent.
Design and development of a medical device is an exacting process, to say the least, and it assumes even more complexity because it almost always extends across years that encompass multiple iterations of the device. As a result, small things that were satisfactory in the prototype and first production run can grow to be problems that must be solved as production volume rises.
The conference program for MEDICA 2013, International Trade Fair with Congress – World Forum for Medicine, is undergoing a full re-launch. The content repositioning for MEDICA 2013 (to be held from November 20 – 23, 2103 in Düsseldorf, Germany) is designed to closely fit the program of the trade fair’s topics relevant to medical equipment users and to expand the international side of the program.
Neuroscientists may soon be modern-day harpooners, snaring individual brain-cell signals instead of whales with tiny spears made of carbon nanotubes. The new brain cell spear is a millimeter long, only a few nanometers wide and harnesses the superior electromechanical properties of carbon nanotubes to capture electrical signals from individual neurons.
Duke University biomedical engineers and genome researchers have developed a proof-of-principle approach using light to detect infections before patients show symptoms. The approach was demonstrated in human samples, and researchers are now developing the technique for placement on a chip, which could provide fast, simple and reliable information about a patient.
A landmark three-dimensional (3-D) digital reconstruction of a complete human brain, called the BigBrain, now for the first time shows the brain anatomy in microscopic detail—at a spatial resolution of 20 microns, smaller than the size of one fine strand of hair—exceeding that of existing reference brains presently in the public domain.
Lumosity, the leading brain training company, today announced a new web-based, big data methodology for conducting human cognitive performance research. Lumosity's research platform, the Human Cognition Project, contains the world's largest and continuously growing dataset of human cognitive performance, which currently includes more than 40 million people who have been tracked for up to 6 years.
A more accurate and reliable stroke prediction model has been developed to help physicians decide whether to start blood-thinning treatment for patients with atrial fibrillation, as described in the current online issue of the Journal of the American Heart Association.
A team of NUS researchers from the Departments of Bioengineering and Orthopaedic Surgery has developed a highly realistic three-dimensional (3D) tumour model. As it replicates the conditions in the body, it is able to track the effectiveness and progress of drug therapy.
Techne, which makes medical testing and diagnostic products, said Tuesday that it reached a deal to buy Bionostics Holdings Ltd. and its operating subsidiary Bionostics Inc. for $104 million in cash.
Researchers in the University’s Physics and Pharmacy & Pharmacology Departments are using a pioneering technique to study the properties and characteristics of our skin, in tests that could pave the way for new treatments for dermatitis, and for an improved understanding of the skin ageing process.
Out in the wilds or anywhere off the grid, sophisticated instruments small enough to fit in a shirt pocket will one day scavenge power from sunlight, body heat, or other sources to monitor water quality or bridge safety or function as wearable biomedical monitors, enabling analysis in the field rather than bringing samples and data back to the lab.
A medical test previously developed to measure a toxin found in tobacco smokers has been adapted to measure the same toxin in people suffering from spinal cord injuries and multiple sclerosis, offering a potential tool to reduce symptoms.
The Supreme Court ruled Thursday that companies cannot patent parts of naturally-occurring human genes, a decision with the potential to profoundly affect the emerging and lucrative medical and biotechnology industries. The high court's unanimous judgment reverses three decades of patent awards by government officials.
According to new research from the Monell Center and collaborating institutions, odors from human skin cells can be used to identify melanoma, the deadliest form of skin cancer. In addition to detecting a unique odor signature associated with melanoma cells, the researchers also demonstrated that a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells.
Supreme Court Ruling Today Allows DNATraits to Offer Low Cost BRCA Breast and Ovarian Cancer Gene Testing in U.S.June 13, 2013 2:09 pm | by PR Newswire | News | Comments
Thanks to today's U.S. Supreme Court decision opening the door to greater access to genetic medicine by American patients and their health care providers, testing for genes specifically linked to breast, ovarian and other cancers will now be more widely available and at a lower cost than ever before.
A new University of Florida study suggests a promising brain-imaging technique has the potential to improve diagnoses for the millions of people with movement disorders such as Parkinson’s disease. Utilizing the diffusion tensor imaging technique, as it is known, could allow clinicians to assess people earlier, leading to improved treatment interventions and therapies for patients.
When you squeeze something, it gets smaller. Unless you’re at Argonne National Laboratory. At the suburban Chicago laboratory, a group of scientists has seemingly defied the laws of physics and found a way to apply pressure to make a material expand instead of compress/contract.
Genetic variations, known as single nucleotide polymorphisms (SNPs), in or near the genes ZNF423 and CTSO were associated with breast cancer risk among women who underwent prevention therapy with tamoxifen and raloxifene, according to data published in Cancer Discovery, a journal of the American Association for Cancer Research.
On this episode of The Pulse, rewired nerves from amputated limbs allow for prosthetic control with existing muscles, a bioengineered blood vessel is transplanted, diabetes is diagnosed through breath analysis alone, and a new technology is paving the way for low-cost electronic devices that work in direct contact with living tissue inside the body.
Today's technological innovation enables smartphone users to diagnose serious diseases such as diabetes or lung cancer quickly and effectively by simply breathing into a small gadget, a nanofiber breathing sensor, mounted on the phones. Il-Doo Kim, Associate Professor of Materials Science and Engineering Department at the Korea Advanced Institute of Science and Technology...
Professor Il-Doo Kim of Materials Science & Engineering, KAIST, developed an exhaled breath sensor that is composed of highly porous tin dioxide (SnO2) nanofibers with a unique nanostructure functionalized by catalytic platinum (Pt) particles. This unique structure reacts to acetone gas, which is known as a biomarker of diabetes, for the fast diagnosis of the disease within 10 seconds.
Diagnostic technology covers a broad range of equipment, tests, and medical fields, and recent advancements in technique and materials means that innovations are widespread and growing rapidly. Though economic conditions are preventing huge advancements in diagnostic imaging—if hospitals can’t afford the new technology, there is no point in designing it—the medical imaging community is focusing on refinement, rather than redesign.
