Scientists use magnetic nanotech to safely rewarm frozen tissues for transplant

17-Sep-2024 - Every day, people die waiting for an organ transplant. Time is at a premium, not just for those awaiting organs, but also for the organs themselves, which can deteriorate rapidly during transportation. Looking to extend the viability of human tissues, researchers report in ACS’ Nano Letters their ...

A Delivery Service for Insulin

It's an old dream in pharmacy: to deliver an active ingredient to the exact place in the body where it is most needed

12-Jul-2024 - Up to three percent of people with diabetes have an allergic reaction to insulin. A team at Forschungszentrum Jülich has now studied a method that could be used to deliver the active substance into the body in a masked form - in the form of tiny nanoparticles. The insulin is only released in the ...

The virus hackers: RNAi therapy for viral respiratory diseases

Inhalation as a silver bullet

05-Feb-2024 - A research team from the Fraunhofer Institute for Toxicology and Experimental Medicine ITEM and the Hannover Medical School (MHH) have made significant progress in developing a new antiviral therapy. The drug, which is inhaled, uses RNAi to target and deactivate parainfluenza viruses before they ...

Medically relevant nanoparticles move faster in cells than expected

Finding has large implications for applications in nanomedicine such as targeted drug delivery and intracellular studies

10-Jan-2024 - An experiment led by a team of DESY and Universität Hamburg scientists has discovered that gold nanoparticles can move through liquid biological matter faster than expected when coated by the polymer polyethylene glycol (PEG). The team’s data, which were acquired using X-ray photon correlation ...

Nanoparticles for optimized cancer therapy

Innovative method holds promise for more targeted treatment with fewer side effects - spin-off aims to quickly bring nanoparticles into clinical use

17-Nov-2023 - Pancreatic cancer is one of the deadliest types of cancers in humans. It is the fourth leading cause of cancer-related deaths in the western world. The early stages of the disease often progress without symptoms, so diagnosis is usually very late. Another problem: Advanced tumors – and their ...

New study on the genetic magnetization of living bacteria

Great potential for biomedicine

25-Sep-2023 - Magnetic bacteria possess extraordinary capabilities due to the magnetic nanoparticles, the magnetosomes, which are concatenated inside their cells. A research team at the University of Bayreuth has now transferred all the about 30 genes responsible for the production of these particles to ...

New compound unleashes the immune system on metastases

A new nanocomplex renders a tumor harmless – and, on top of that, it trains the immune system to detect and eliminate metastases

08-Sep-2023 - An international research team headed by Dr. Johannes Karges of the Faculty of Chemistry and Biochemistry at Ruhr University Bochum, Germany, has developed nanoparticles that accumulate in cancer cells and eliminate them after being photoactivated. In addition, they label them in such a way that ...
