Phonon Probe to Image Tissues Ultrasonically at Nanoscale

Visual signs of disease can often be spotted within affected tissues, and advances in histopathology have provided clinicians with powerful diagnostic tools to spot those signs. Microscopes are the cornerstone of this trade, and although they have proven to be extremely useful, they do suffer from some limitations. They are effectively 2D imaging d (Read more...)

New Software Helps Design DNA Nanorobots

Researchers at Ohio State University have developed new software that allows them to rapidly design and simulate DNA nanorobots. Previously, it was challenging to engineer such tiny devices, but now researchers can map out their design in minutes. DNA-based devices have significant promise as medical technologies with potential applications in drug (Read more...)

Artificial Attachments for Immune Cells Help Kill Tumors

Though immune cells have the capabilities to kill cancer cells, they’re often thwarted by cancer’s ability to evade detection. Researchers at Pennsylvania State University have now developed engineered natural killer cells that have a much better ability to find and kill cancerous cells. “We explored a novel method to engineer nat (Read more...)

Microbubbles Deliver Drugs Directly to Tumors

When fighting cancerous tumors, all too often the very drugs that can destroy a lesion tend to have significant negative effects on the rest of the body. Doses have to be maintained at moderate levels to avoid side-effects that are even worse than the disease. In light of this, researchers have been trying to develop […]

Inhalable Nanobody Therapy Deactivates SARS-CoV-2

Researchers at the University of Pittsburgh have developed a new antibody-type therapy for SARS-CoV-2, the causative virus for COVID-19. The treatment exploits “nanobodies” – tiny antibody fragments – that are harvested from llama blood. The new nanobody therapy can be used in an inhalable form that may deactivate the virus (Read more...)

Body Sensors Printed Directly on Skin at Room Temperature

Biomedical sensors typically perform their best when they’re placed in close proximity to the body. While wearables, such as wrist-worn heart rate monitors, are common these days, they are very limited by where they can be placed on the body, have poor signal quality, and are often uncomfortable to wear for extended periods. Now, researchers (Read more...)

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...)
