Researchers have developed the world's tiniest engine - just a few billionths of a metre in size - which uses light to power itself. The nanoscale engine, developed by researchers at the University of Cambridge, could form the basis of future nano-machines that can navigate in water, sense the environment around them, or even enter living cells to fight disease.
Researchers at MIT and Brigham and Women's Hospital have developed nanoparticles that can deliver antiobesity drugs directly to fat tissue. Overweight mice treated with these nanoparticles lost 10 percent of their body weight over 25 days, without showing any negative side effects.
The fabrication of a prototype tissue having functional properties close to the natural ones is crucial for effective transplantation. Tissue engineering scaffolds are typically used as supports which allow cells to form tissue-like structures essentially required for the correct functioning of the cells under the conditions close to the three-dimensional tissue.
Insulin deficiency and hyperglycemia are two well-known culprits behind diabetes, both of which are reflected in blood glucose concentrations. Now, researchers are working to create ultrasensitive lab-on-a-chip devices to quickly measure glucose concentrations with the goal of developing device for early diagnosis and prevent of diabetes.
A microscope about the size of a penny is giving scientists a new window into the everyday activity of cells within the spinal cord. The innovative technology revealed that astrocytes--cells in the nervous system that do not conduct electrical signals and were traditionally viewed as merely supportive--unexpectedly react to intense sensation.
Researchers from the University of Washington's Department of Mechanical Engineering, in collaboration with partners from Gillette Children's Specialty Healthcare, have developed a new quantitative assessment of motor control in children with cerebral palsy called Walk-DMC, which could help predict which patients are -- or are not -- likely to benefit from such aggressive treatment.
Researchers at University of Montreal have created a programmable DNA thermometer that is 20,000x smaller than a human hair. This scientific advance reported this week in the journal Nano Letters may significantly aid our understanding of natural and human designed nanotechnologies by enabling to measure temperature at the nanoscale.
Researchers at Ben-Gurion University of the Negev (BGU) have developed an innovative anti-biofilm coating, which has significant anti-adhesive potential for a variety of medical and industrial applications.
Chinese scientists developed a facile approach for the rapid and maskless fabrication of bio-inspired hierarchical structures using multi-beam laser interference, demonstrating its potential in large-area, low-cost and high-volume 3-D fabrication.
Blood-contacting implantable medical devices, such as stents, heart valves, ventricular assist devices, and extracorporeal support systems, as well as vascular grafts and access catheters, are used worldwide to improve patients' lives.
SIRKA: this acronym stands for "sensor suit for individual feedback of physical activity". In a joint project, the DFKI is developing a suit designed to prevent problems with poor posture. Inertial sensors are integrated into a work overall. Physiotherapists are also meant to benefit from the results.
The trend towards miniaturization is progressing in medical technology. This in turn also means that electronics must be adapted to size relations, for example of implants. Smaller structures and components are in demand as never before. Thus, the demands on the technology and production simultaneously grow.
