Now you can build your own low-cost 3-D bioprinter by modifying a standard commercial desktop 3-D printer for under $500 — thanks to an open-source “LVE 3-D” design developed by Carnegie Mellon University (CMU) researchers. CMU provides detailed instructional videos. You can print artificial human tissue scaffolds on a larger scale (entire human heart) [...]
A new method to sensitively measure the structure of molecules has been demonstrated by twisting laser light and aiming it at miniscule gold gratings to separate out wavelengths. The technique could potentially be used to probe the structure and purity of molecules in pharmaceuticals, agrochemicals, foods and other important products more easily and cheaply [...]
Researchers at the University of Toronto have developed a new technology for a “liquid biopsy” to identify which patients might not respond to standard therapy for prostate cancer before it is delivered. Prostate cancer is the second most common cancer in men and the fifth leading cause of death from cancer in men worldwide, [...]

Optics & Photonics is known as the premier show in North America for the latest advancements in optical engineering and applications, nanotechnology, sustainable energy, organic photonics, and astronomical instrumentation. In San Diego next week, PI’s booth will feature the latest state-of-the-art precision motion technologies and interactive displays of nanopositioning components, with [...]
In a quest to make more realistic, safer, and personalizable tissue replacement implants, bacterial cellulose nanofibers are being looked on as a viable material. They are naturally biocompatible, biodegradable, withstand heat well, and have physical properties similar to many of our tissues, when composed into larger objects. Bacterial cellulose nanofibers are produced by aerobic [...]
Researchers have developed a process for creating ultrathin, self-assembling sheets of synthetic materials that can function like designer flypaper in selectively binding with viruses, bacteria, and other pathogens. In this way the new platform, developed by a team led by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), could [...]
Studies have shown that the wings of dragonflies and cicadas prevent bacterial growth due to their natural structure. The surfaces of their wings are covered in nanopillars making them look like a bed of nails. When bacteria come into contact with these surfaces, their cell membranes get ripped apart immediately and they are killed. [...]
A group of researchers headed by the Department of Energy’s Oak Ridge National Laboratory has discovered an innovative method to find out the local temperature of a material from an area with a width of just one-billionth of 1 m, or roughly 100,000 times thinner than a strand of human hair. This finding has [...]
Tiny floating robots could be useful in all kinds of ways, for example, to probe the human gut for disease or to search the environment for pollutants. In a step toward such devices, researchers describe a new marriage of materials, combining ultrathin 2-D electronics with miniature particles to create microscopic machines. The researchers will [...]
