Bioengineers have shown that a new strategy can restore damaged stem cells and enable them to grow new tissues again. The new drug delivery system could help infants born from complicated pregnancies.

Researchers have succeeded in amplifying the nonlinear response using artificial chiral metamaterial. The new technology enhances the possible applications of mirror symmetry by amplifying chiral nanoparticle signals.

Within a newborn's umbilical cord lie potentially life-saving stem cells that can be used to fight diseases like lymphoma and leukemia. That is why many new parents elect to store ("bank") their infant's stem cell-rich umbilical cord blood. But in the 6–15% of pregnancies affected by gestational diabetes, parents lack this option because the condition damages the stem cells and renders them useless.

Northwestern Medicine investigators have developed a novel nanoparticle treatment for glioblastoma, according to a study published in Nature Communications.

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see.

MIT Associate Professor Robert Macfarlane is uncovering design principles that allow researchers to fine-tune materials at many size scales.

Typically, researchers attempting to synthesize specifically targeted particles of materials have had to rely on intuition or trial-and-error methods. This approach can be inefficient, requiring significant time and resource investments.

The Centers for Disease Control and Prevention estimates that more than 2.8 million Americans experience antibiotic-resistant infections each year; more than 35,000 die from those infections.

In mice and human cell cultures, MIT researchers showed that lipid nanoparticles can deliver a potential RNA therapy for inflammation in the brain, a prominent symptom in Alzheimer's disease.

A team of researchers, including members from the University of Connecticut, has developed a nanoparticle-based treatment that targets multiple culprits in glioblastoma, a particularly aggressive and deadly form of brain cancer.

The old adage that oil and water don't mix isn't entirely accurate. While it's true that the two compounds don't naturally combine, turning them into one final product can be done. You just need an emulsifier, an ingredient commonly used in the food industry.

Baker Heart and Diabetes Institute researchers have designed and developed a novel drug delivery method that can vastly improve the efficacy of a drug used to treat atherosclerosis and has the potential to identify and treat other diseases.

Many different types of bacteria and viruses can cause pneumonia, but there is no easy way to determine which microbe is causing a particular patient's illness. This uncertainty makes it harder for doctors to choose effective treatments because the antibiotics commonly used to treat bacterial pneumonia won't help patients with viral pneumonia. In addition, limiting the use of antibiotics is an important step toward…

Despite gaining a bad rap in mainstream media in recent years, nanoparticles have been successfully used for decades in targeted drug delivery systems. Drug molecules can be encapsulated within biodegradable nanoparticles to be delivered to specific cells or diseased tissues. However, blood flow dynamics can significantly affect the nanoparticle's ability to bind at the target site and stay adhered long enough for…

A novel cancer therapeutic, combining antibody fragments with molecularly engineered nanoparticles, permanently eradicated gastric cancer in treated mice, a multi-institutional team of researchers found.

In a study published July 29 in Advanced Materials, University of Texas at Dallas researchers found that X-rays of the kidneys using gold nanoparticles as a contrast agent might be more accurate in detecting kidney disease than standard laboratory blood tests. Based on their study in mice, they also found that caution may be warranted in employing renal-clearable nanomedicines to patients with compromised kidneys.

Nanoparticles consisting of a designer protein that counteract an overreaction of the immune system, while simultaneously boosting that system. This invention offers possibilities for the treatment of sepsis, a condition in which the immune system is severely dysregulated.

Two newly developed, low-cost tests that use nanoparticles to detect chemicals can accurately measure tiny amounts of two potentially harmful herbicides in fruits, vegetables and their products.
