Researchers have developed a rapid color-changing test that can distinguish between different strains of golden staph, including those likely to be virulent and antibiotic resistant. Golden staph is a major human pathogen and is a leading cause of infection-related deaths globally, with more than a million fatalities each year. The research paper is published in the journal Small. https://phys.org/news/2026-04-dangerous-staph-strains-fast.html Bio & Medicine Wed, 15 Apr 2026 17:20:09 EDT news695481241 Nanozymes are synthetic materials that have enzyme-like catalytic properties, and they are broadly used for biomedical purposes, such as disease diagnostics. However, inorganic nanozymes are generally toxic, expensive, and complicated to produce, making them unsuitable for the agricultural and food industries. https://phys.org/news/2025-02-generation-nanozymes-safe-effective-solution.html Bio & Medicine Thu, 27 Feb 2025 17:07:04 EST news659898422 Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. https://phys.org/news/2024-07-nanozymes-broad-applications-food-agriculture.html Biochemistry Tue, 30 Jul 2024 12:18:37 EDT news641560711 Chemotherapy is a mainstay of cancer treatment. While effective, this therapy indiscriminately kills rapidly dividing cells—cancerous or otherwise—so patients frequently experience severe side effects, ultimately limiting its utility. https://phys.org/news/2023-08-nanozymes-tumor-specific-drug-delivery-minimizing.html Bio & Medicine Wed, 09 Aug 2023 13:37:02 EDT news610807017 A growing body of evidence points to a link between iron-deficiency anemia and severe tooth decay. Whether the connection is correlative or causative is unknown, though both conditions are associated with poor diets and are more common in people living in impoverished environments and with underlying medical conditions. https://phys.org/news/2021-10-nanozyme-therapy-dental-plaque-build-up.html Bio & Medicine Tue, 26 Oct 2021 03:34:42 EDT news554438078 In a significant breakthrough in the battle against antibiotic resistance, a research team from the Indian Institute of Science (IISc) has synthesized a nanomaterial that mimics an enzyme and can disintegrate the cell membranes of a range of disease-causing bacteria. The study, published in the journal ACS Applied Bio Materials, is a collaboration between researchers from the Department of Inorganic and Physical Chemistry (IPC) and the Department of Microbiology and Cell Biology (MCB). https://phys.org/news/2020-06-nanomaterials-broad-spectrum-antimicrobial-agents.html Bio & Medicine Tue, 23 Jun 2020 07:14:06 EDT news512115240 Nanozymes are catalytic nanomaterials with enzyme-like characteristics that have attracted enormous recent research interest. The catalytic nanomaterials offer unique advantages of low cost, high stability, tunable catalytic activity and ease of mass production and storage. These properties are highly desirable for a wide range of applications in biosensing, tissue engineering therapeutics and environmental protection. However, conventional nanozyme technologies face critical challenges relative to their size, composition and facet-dependent catalysis, in addition to inherently low active site density. https://phys.org/news/2019-05-single-atom-nanozymes.html Nanomaterials Tue, 14 May 2019 09:30:01 EDT news476949773 Nanozymes—catalytic nanomaterials with enzyme-like characteristics—offer the advantage of low cost, high stability, tunable catalytic activity and ease of mass production.

Until now, lots of nanomaterials have been explored to mimic various natural enzymes, such as peroxidase, oxidase, catalase, and hydrolase. Particularly, enormous efforts have been devoted to peroxidase-like nanozymes because of their applications in biomedical diagnosis, bioimaging, anti-biofouling coatings, etc. https://phys.org/news/2019-02-principles-peroxidase-mimicking-nanozymes.html Biochemistry Mon, 18 Feb 2019 08:50:03 EST news469701803 Researchers from RMIT University have developed a new artificial enzyme that uses light to kill bacteria. https://phys.org/news/2018-04-nanozymes-bacteria.html Bio & Medicine Wed, 04 Apr 2018 16:27:47 EDT news442078059
