These heavy metals are an indispensable part of many industries. However, they also share a dark reality: They are serious environmental and public health threats. Every day, they find their way into the atmosphere and water bodies through industrial activities, mining and urban waste. Heavy metals are highly toxic, do not break down naturally and tend to build up in the tissues of living organisms over time. https://phys.org/news/2026-06-medicinal-yield-carbon-nanoparticles-red.html Bio & Medicine Mon, 08 Jun 2026 16:50:01 EDT news700154762 The fixed idea that DNA is only a molecule that stores genetic information is being challenged. KAIST researchers have developed a technology that controls the chemical environment around catalysts at the nanometer scale by designing DNA sequences—the arrangement of A, T, G and C that make up genetic information. The team has presented a new catalyst platform that can improve hydrogen production efficiency and increase the yield of desired chemical products by designing DNA much like writing a computer program. https://phys.org/news/2026-06-dna-nanometer-scale-catalyst-cleaner.html Bio & Medicine Mon, 08 Jun 2026 16:10:06 EDT news700152361 Computational point-of-care sensors can significantly improve access to diagnostics by enabling rapid patient testing outside centralized medical facilities. These tests rely on machine learning models to make diagnostic predictions, but such inference models are susceptible to hallucinations and may produce erroneous outcomes. As a result, their limited reliability has partially hindered the broader adoption of computational sensors in health care settings. https://phys.org/news/2026-06-autonomous-ai-screening-flags-unreliable.html Bio & Medicine Sun, 07 Jun 2026 07:00:01 EDT news700031733 Imagine a future where cancer treatment affects only the tumor, where eye injections are no longer required and brain surgeries don't result in large incisions or long recovery times. That's the future researchers at Michigan State University are working toward. https://phys.org/news/2026-06-hair-size-microrobots-combine-cancer.html Bio & Medicine Sat, 06 Jun 2026 11:00:03 EDT news699627985 The CIC biomaGUNE Center for Cooperative Research in Biomaterials has developed pulmonary surfactant nanoparticles (the blend of lipids and proteins that line the alveoli and enables breathing), which are encapsulated in a drug used to treat pulmonary fibrosis. The researchers show that these nanoparticles are highly capable of remaining trapped in the diseased tissue after being administered via the pulmonary pathway. This allows the doses of antifibrotic medication to be cut, and thus reduces the potential side effects associated with conventional therapies. Tests carried out on mice displayed a therapeutic effect on pulmonary fibrosis. https://phys.org/news/2026-06-nanoparticles-lung-fluid-therapies-respiratory.html Bio & Medicine Thu, 04 Jun 2026 19:20:04 EDT news699805562 Graphene, the "wonder material," has shaped much of Suprem Das's research career.

Nerve cells in the spinal cord rarely regenerate naturally, while scarring often prevents the regrowth of nerve fibers. Modern therapies attempt to influence implanted stem cells using electrical stimulation to promote the growth of new nerve cells. This approach has several drawbacks: it requires implanted electrodes, and the transplanted cells do not always survive or integrate properly into the existing tissue. https://phys.org/news/2026-06-biohybrid-microrobots-spinal-cord-combining.html Bio & Medicine Tue, 02 Jun 2026 09:40:01 EDT news699610321 Lung cancer remains one of the world's deadliest cancers, yet despite decades of effort to develop new drugs, many fail because they don't stay in the body long enough to be effective or because they damage healthy organs. Now, Adelaide University researchers have developed a novel nanoparticle "delivery vehicle" that precisely targets cancer drugs to the lungs while helping to limit harmful side effects—a breakthrough that could reshape how the disease is treated. https://phys.org/news/2026-06-nanoparticles-boost-delivery-lung-cancer.html Bio & Medicine Tue, 02 Jun 2026 09:20:04 EDT news699610261 Researchers with the University of Cincinnati and Johns Hopkins Medicine developed a potential treatment for brain cancer that uses nanofibers embedded with a combination of drugs that work in concert to target tumors.

While treatment is often successful, bladder cancer has one of the highest rates of recurrence of any cancer: Following treatment, about 50% of patients develop tumors again within the next five years. This makes it one of the most expensive cancers for society to treat. https://phys.org/news/2026-05-nanotube-coated-catheter-bladder-cancer.html Bio & Medicine Thu, 28 May 2026 15:10:01 EDT news699198481 Researchers at The University of Texas at Austin have uncovered key principles that govern how DNA "origami" structures fold, findings that could make nanoscale materials faster and easier to manufacture.

These aggregates are associated with cellular dysfunction and lead to progressive neuronal loss. Because current treatments only manage symptoms rather than stopping the underlying protein clumping, scientists are exploring new strategies, including nanomaterials that can prevent these aggregates from forming or help clear them from the brain. https://phys.org/news/2026-05-graphene-quantum-dots-parkinson-protein.html Bio & Medicine Sun, 24 May 2026 18:30:02 EDT news698487434 Precision medicine aims to transport therapeutic agents, such as molecules, proteins or RNA, to the exact place where they need to act within the body. One of the most promising strategies is the use of nanocarriers: nanoparticles capable of encapsulating the drug, protecting it, transporting it and releasing it in a controlled manner where it is needed. At present, however, their behavior is usually analyzed using techniques based on average measurements of large populations, which conceal the differences between individual particles. https://phys.org/news/2026-05-particle-tracking-reveals-uneven-nanoparticle.html Bio & Medicine Thu, 21 May 2026 17:50:01 EDT news698601481 Living systems such as cells rely on membrane pores and channels to transport molecules, exchange signals, and organize biochemical reactions.

Research published in the Journal of Controlled Release addresses that problem with a fundamentally new strategy: instead of simply increasing drug doses or switching drugs, researchers engineered nanoparticles that first disable the cancer cell's drug-expulsion mechanism, and only then release the anticancer drug. https://phys.org/news/2026-05-nanoparticles-drug-resistant-cancer-sequential.html Bio & Medicine Fri, 08 May 2026 11:20:05 EDT news697457282 A research team led by the University of Michigan College of Pharmacy and the University of Texas MD Anderson Cancer Center has developed a new type of nanoparticle therapy that could make cancer immunotherapy safer and more effective.
