The EVONANO platform allows scientists to grow virtual tumours and use artificial intelligence to automatically optimise the design of nanoparticles to treat them.
When medical isotopes are used to treat diseases, they emit large amounts of energy that makes it hard to keep them near the target cells. Researchers are now testing a way to enclose isotopes in tiny pieces of biodegradable material that will keep the isotopes at treatment sites, ensuring that their energy can kill diseased cells with little effect on surrounding cells.
Using a virus that grows in black-eyed pea plants, researchers developed a new therapy that could keep metastatic cancers from spreading to the lungs, as well as treat established tumors in the lungs.
Chula researchers celebrate the success of Active Targeting, a revolutionary innovation in the medical industry using bio–robots to deliver targeted cordyceps extract to halt cancer with reduced side effects.
Scientists at Berkeley Lab and UC Berkeley have developed a nanoparticle composite that grows into 3D crystals. The new 3D-grown material could speed up production and eliminate errors in the mass manufacturing of nanoscale photonics for smart buildings or actuators for robotics.
Nanoengineers at the University of California San Diego have developed immune cell-mimicking nanoparticles that target inflammation in the lungs and deliver drugs directly where they’re needed. As a proof of concept, the researchers filled the nanoparticles with the drug dexamethasone and administered them to mice with inflamed lung tissue. Inflammation was completely treated in mice given the nanoparticles, at a drug concentration where standard delivery methods did not have any efficacy.
Chula Veterinary Science lecturer develops biorobots, made from safe and effective materials, to deliver time-released nutrients to the body, adding value to Thai herbs.
A team of neuroscientists and engineers at McMaster University has created a nasal spray to deliver antipsychotic medication directly to the brain instead of having it pass through the body.
University at Buffalo researchers are reporting an advancement of a chemical sensing chip that could lead to handheld devices that detect trace chemicals — everything from illicit drugs to pollution — as quickly as a breathalyzer identifies alcohol.
One of the proteins on the virus – located on the characteristic COVID spike – has a component called the receptor-binding domain, or RBD, which is its “Achilles heel.” That is, he said, antibodies against this part of the virus have the potential to the neutralize the virus.
A team of scientists led by the U.S. Department of Energy’s Ames Laboratory has developed a first-of-its-kind catalyst that is able to process polyolefin plastics, types of polymers widely used in things like plastic grocery bags, milk jugs, shampoo bottles, toys, and food containers.
A team of researchers at the University of Chicago have developed a self-assembling nanoparticle to create a toolbox for treating infections such as Toxoplasma gondii, a serious parasitic infection.
A University of Delaware research team has devised tiny cargo-carrying systems many times smaller than a human hair, made from molecules called peptides that help provide structure for cells and tissues. The team has reported advances in the nanoparticle design that allow them to control the shape of the nanoparticles to allow them to better bind to tissue in the body and stay in a particular location.
Researchers reporting in ACS Central Science developed an injectable hydrogel that allows sustained release of vaccine components, increasing the potency, quality and duration of immune responses in mice.
Nanoparticles cloaked in human lung cell membranes and human immune cell membranes can attract and neutralize the SARS-CoV-2 virus in cell culture, causing the virus to lose its ability to hijack host cells and reproduce.
Most commercial nanoparticles do not possess a single magnetic core but have small magnetic crystals called crystallites. The important question is how these crystallites behave inside a multicore nanoparticle and how they respond to an applied magnetic field. In the Journal of Applied Physics, researchers compare the effective magnetic moments of different multicore nanoparticle systems and shows that they are magnetic-field dependent. The paper’s findings are important for researchers optimizing magnetic nanoparticles for various applications.
Scientists have discovered a new method of producing ultra-thin porous membranes. The key is growth of a polymer “corona”—an ultrathin layer of polymer surrounding highly porous metal-organic-framework (MOF) nanoparticles. The nanoparticles self-assemble into layers one particle thick and into multilayer, self-supporting porous films.
A new grant from the US Department of Defense will help a University of Delaware team test a novel technology that uses iron nanoparticles to destroy munitions compounds in wastewater.
Scientists report progress toward a new type of ceramic glaze that includes gold and silver nanoparticles, which are less toxic and more environmentally friendly, while still providing vibrant colors. The researchers are presenting their results through the ACS SciMeetings online platform.
Scientists at Johns Hopkins report they have designed and successfully tested an experimental, super small package able to deliver molecular signals that tag implanted human cancer cells in mice and make them visible for destruction by the animals’ immune systems. The new method was developed, say the researchers, to deliver an immune system “uncloaking” device directly to cancer cells.
Scientists can control their branch sizes and surfaces to make them more stable and more effective catalysts. By creating branched nanoparticles from the metal ruthenium, researchers developed a way to increase the speed of catalysis while maintaining the catalyst’s stability.
A new study at the University of Georgia has found a way to attack cancer cells that is potentially less harmful to the patient.
This new research shows how the ligands affect key structural and mechanical properties of the superlattices.
The December 2019 issue of Toxicological Sciences features research on the leading edge of toxicology, including in the areas of carcinogenesis, developmental and reproductive toxicology, and more.
An international team of researchers has used nanoparticles to deliver a drug—one that previously failed in clinical trials for pain—into specific compartments of nerve cells, dramatically increasing its ability to treat pain in mice and rats. The findings are published Nov. 4 in Nature Nanotechnology.
A team of scientists led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has gained valuable insight into 3D transition metal oxide nanoparticles’ natural “edge” for 2D growth.
