Synthetic Peptides Jump Around to Repair Spinal Injuries

Researchers at Northwestern University have developed an injectable therapeutic that consists of synthetic peptide sequences intended to regenerate spinal tissue. The team designed the material so that it would allow the peptides to ‘dance,’ with such movements increasing the chance that they will find and interact with receptor protein (Read more...)

Carbon Nanotube Sensor Detects SARS-CoV-2 Within 5 Minutes

Scientists at MIT announced the development of a rapid COVID-19 test that can detect the virus in a saliva sample in as little as five minutes. The technology does not require antibodies or other expensive reagents typically associated with protein detection, and is instead based on carbon nanotubes. The nano-structures are encased in a web [&helli (Read more...)

Iron Oxide Nanoparticles Suppress Oral Biofilms

Collaborators from University of Pennsylvania and Indiana University have tested a ‘”nanozyme” system designed to reduce dental plaque. The technology consists of iron oxide nanoparticles that are applied to tooth enamel before a follow-up rinse of hydrogen peroxide. The nanoparticles act as an “enzyme” to activate the (Read more...)

Carbon Nanotube Thread Lets Clothes Monitor Health

Researchers at Rice University managed to create flexible carbon nanotube fibers that can be incorporated into clothing to function as wearable health monitors. The new thread is highly conductive, but it is washable and strong, allowing it to function as an unobtrusive component of clothing. So far, the researchers have incorporated the fibers int (Read more...)

Nanoparticles for Tumor Imaging and Cancer Urine Testing

Scientists at MIT have announced that they developed novel nanoparticles to detect cancer in urine samples. As well as detecting the presence of tumors, the nanoparticles can also accumulate at tumor sites and function as an imaging agent, helping to identify their location. These multifunctional particles could be very useful for routine cancer sc (Read more...)

DNA Origami to Trap Viruses Inside Body

Researchers at the Technical University of Munich have developed a method to create tiny virus traps that can bind viral particles and render them harmless within the body. The technique relies on DNA origami to create self-assembling hollow nanocapsules, which are lined with molecules that will bind viruses and prevent them from leaving. With a [& (Read more...)

Microchip Nanosensor Detects Stress Hormone from Drop of Blood

Researchers at Rutgers University have developed a microchip that can perform real-time measurements of stress hormone levels in a drop of blood. The technology could provide a replacement for bulky and expensive lab tests for such hormones, and allow patients to monitor their stress levels more easily. The chip includes tiny wells that contain ant (Read more...)

Fluorescent mRNA to Track, Optimize Delivery

Researchers at Chalmers University of Technology in Sweden and collaborators created a technique to produce fluorescently labeled mRNA, allowing them to track its entry and distribution into cells. Using such molecules could help scientists develop better ways to deliver mRNA therapeutics into the body, potentially playing a vital role in the new w (Read more...)

Nanodecoys Bind SARS-CoV-2 for Destruction by Immune System

Researchers at North Carolina State University have developed a nanodecoy system that provides binding sites for the SARS-CoV-2 virus. The vesicles help to prevent the virus from binding to lung cells and lead to its eventual destruction by the immune system. The nanodecoys are derived from lung spheroid cells, and contain the angiotensin-convertin (Read more...)

Gene-Silencing Nanoparticles to Treat COVID-19

Researchers at City of Hope, a research center based in California, and Griffith University in Australia have collaborated to create a new experimental anti-viral therapy that can treat COVID-19. The therapeutic consists of small interfering RNA (siRNA) molecules encapsulated within lipid nanoparticles. When delivered into the bloodstream, the nano (Read more...)

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 […]
