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 ...

Measuring particle size distribution during the grinding process

A further step toward a stable measurement method for nanoparticles used in industry

26-Jul-2024 - How pharmaceuticals act, how efficient catalysts are and how effective and accurate printing inks function all depend on the size of the nanoparticles they contain. However, there are as of yet no methods for monitoring the particle size distribution during grinding processes. In the EU-funded ...

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 ...

Fast, robust series production of nanoparticles

Next-generation encapsulation technology

08-May-2024 - Nucleic acid-based medications such as mRNA vaccines offer tremendous potential for medicine and are opening up new therapeutic approaches. These active ingredients must be enclosed inside nanoparticles to ensure that they get to where they are needed inside the body’s cells. The Fraunhofer ...

Rechargeable nanotorch

Afterglow luminescence imaging tracks cell-based microrobots in real time

16-Apr-2024 - An afterglow luminescent nanoprobe opens up new possibilities for imaging living cells. As a research team reports in the journal Angewandte Chemie, their new “nanotorch” can continue to luminesce for over ten days after a single excitation. This allows the routes taken through the body by ...

Micro- and nanoplastics in the body are passed on during cell division

That plastic may increase metastasis of tumors

08-Mar-2024 - The gastrointestinal tract is already known to researchers as a major storage site for micro- and nanoplastic particles (MNPs) in the human body. A research consortium consisting of the University of Vienna, the Medical University of Vienna and other partners under the leadership of CBmed GmbH in ...

New approach for fast and cost-effective pathogen detection

Palm-sized test system that can simultaneously carry out up to thirty-two analyses of one sample

09-Feb-2024 - The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team led by Dr. Larysa Baraban at the at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) develops intelligent, miniaturized biosensor devices and ...

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 ...

Glow sticks – Not just for parties anymore

University of Houston researcher using popular party favor to detect biothreats for US Navy

12-Jan-2024 - Remember that party where you were swinging glow sticks above your head or wearing them as necklaces? Fun times, right? Science times, too. Turns out those fun party favors are now being used by a University of Houston researcher to identify emerging biothreats for the United States Navy. It’s ...

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 ...
