Laser-Controlled Microrobots Small Enough for Injections

Microrobotics researchers have been working for decades, in a seemingly futile attempt, to keep up with the miniaturization that has been achieved in the field of microelectronics. Although rudimentary microscopic robots have been developed, they have failed to take full advantage of conventional silicon electronics and so are limited in their func (Read more...)

Nanogenerators Harvest Energy from Body, Monitor Heart Health

Wearable medical devices such as continuous heart rate monitors, insulin pumps, and neural stimulators usually need access to an electric power source in order to function. While there’s a great deal of wasted energy that our body emits that can be harvested to power such devices, making it actually happen using biocompatible materials has pr (Read more...)

Mechanically Stimulating Neurons Using Magnetic Nanodiscs

Electrical stimulation and chemical pharmaceuticals are the two ways that doctors and scientists routinely use to manipulate neural cells. Chemicals have their side effects, are slow to take effect, and are usually systemically delivered, while electrical stimulation usually requires invasive wires, is limited in its resolution, and is nearly impos (Read more...)

Nanostimulators Activate Damaged Tissue to Heal Itself

Peripheral artery diseases and injuries to tissue reduce the amount of oxygen that reaches the affected muscles. Such ischemia is difficult to treat, as new vessels are required to carry more oxygen into damaged tissues. Stem cells derived from fat tissues have been shown to excrete substances that spur angiogenesis and calm nearby inflammation. Bu (Read more...)

Microrobots Roll Along Blood Vessel Walls to Deliver Drugs

Precise delivery of therapeutic drugs into diseased tissue remains a challenge in a variety of cases. Tumors can be hard to seed with chemo agents, particularly when the blood flow is not favorable for delivery. Now, researchers at the Max Planck Institute for Intelligent Systems in Germany have developed microscopic drug delivery devices that can (Read more...)

Nanopropellers to Deliver Gene Therapy Into Cells

Researchers at the Max Planck Institute for Intelligent Systems in Germany have developed powerful nanopropellers that can be steered into the interior of cells to deliver gene therapy. The magnets that these devices, each about the size of a bacteria, are made of were created for the first time for this very task. Most powerful […]

Graphene Biosensor Developed for Rapid COVD-19 Testing

Researchers at the Korea Basic Science Institute, Korea Research Institute of Chemical Technology, and collaborators have published an article on the development of graphene-based test for SARS-CoV-2, the virus causing COVID-19, from nasopharyngeal swabs. They have determined it can detect SARS-CoV-2 in clinical samples at a concentration of 242 co (Read more...)

A Sticky Solution to a Hard Problem : Interview with Dr. Luiz Alavarez, CEO of Theradaptive

The development of biomaterials for orthopedic applications is a crowded space with several large and small companies designing innovative materials. One approach is the use of these materials to deliver therapeutic proteins that enhance healing. Theradaptive has developed a novel method to modify the proteins themselves so that they coat the surfa (Read more...)

Magnetic Beads Trap E. Coli from Body Fluid Samples

While current concern is all about the COVID-19 virus that originated in China and spread around the world, this pathogen will eventually disappear. Escherichia coli (E. coli) bacteria, though, is with us for the long run and it can cause just as much suffering as COVID-19. Researchers at Rutgers University have just reported in journal […]

Spiral Hydroporator To Deliver Nanotechnologies Into Cells

A myriad of different therapeutic, diagnostic, and research-oriented nano-scale devices and molecules have been developed to work inside living cells. While many of these particles are very effective at what they do, it is often the difficulty of delivering them that is the real challenge in using them for practical purposes. Typically, either some (Read more...)

4D Printer to Create Synthetic Biological Surfaces

Researchers at the City University of New York and Northwestern University have developed a printer capable of creating highly detailed surfaces precisely loaded with a variety of organic and biological molecules. The technology allows the researchers to create objects that resemble the surfaces of living cells, something that may prove extremely u (Read more...)

Nanocontainers to Invade Nuclei of Living Cells

The nuclei of cells in our bodies is where much of the important intracellular processes take place. The genomic code is mostly stored within the nucleus and gene expression is controlled there, so getting drugs inside this most important organelle is a long sought goal of many researchers. Some viruses have been used to deliver […]
