Harnessing exosomes and hydrogels for advanced diabetic wound healing Diabetes, a widespread condition affecting approximately 13% of American adults, is often accompanied by complications such as impaired wound healing. If left unchecked, this can lead to severe outcomes, including the need for amputation. /news/2024-09-harnessing-exosomes-hydrogels-advanced-diabetic.html Bio & Medicine Fri, 20 Sep 2024 12:18:58 EDT news646053534 'Tuning' gel-forming protein molecules to boost their versatility for biomedical applications Self-assembling protein molecules are versatile materials for medical applications because their ability to form gels can be accelerated or retarded by variations in pH, as well as changes in temperature or ionic strength. These biomaterials, responsive to physiological conditions, can therefore be easily adapted for applications where their effectiveness depends on gelation kinetics, such as how quickly and under what stimuli they form gels. /news/2022-02-tuning-gel-forming-protein-molecules-boost.html Biotechnology Molecular & Computational biology Wed, 16 Feb 2022 07:37:35 EST news564219453 Colloidal gel properties under the microscope Researchers at the University of Tokyo have devised a method for following the gelation of colloidal gels. Their confocal microscopy technique has allowed the different stages of the process to be analyzed, leading to insights into their mechanical stability. It is hoped that the understanding gained using this technique will contribute to the development of colloidal gels in the many fields in which they impact everyday lives, from pharmaceuticals to construction. /news/2019-05-colloidal-gel-properties-microscope.html Materials Science Fri, 31 May 2019 14:00:02 EDT news478513951 3-D culturing hepatocytes on a liver-on-a-chip device Liver-on-a-chip cell culture devices are attractive biomimetic models in drug discovery, toxicology and tissue engineering research. To maintain specific liver cell functions on a chip in the lab, adequate cell types and culture conditions must be met, which includes 3D cell orientation and a consistent supply of nutrients and oxygen. Compared with conventional 2D cell culture techniques, organ-on-a-chip devices offer versatility and effective biomimicry suited for advanced applications in drug discovery and medicine. /news/2019-01-d-culturing-hepatocytes-liver-on-a-chip-device.html Analytical Chemistry Thu, 17 Jan 2019 09:30:05 EST news466933484 The making of biorelevant nanomaterials The interactions of biological macromolecules such as nucleic acids, proteins, and polysaccharide–protein conjugates can be mimicked by artificial polyelectrolytes. Such synthetic polyionic complexes are expected to serve as novel platforms to stabilize and deliver drugs, proteins, or nucleic acids. In the journal Angewandte Chemie, Chinese investigators have introduced a versatile, commercially applicable preparation strategy of such nanomaterials with tunable morphology. The preparation of libraries of these low-dimensional biorelevant nanostructures can be envisaged. /news/2018-01-biorelevant-nanomaterials.html Nanomaterials Wed, 03 Jan 2018 06:21:59 EST news434182911 Researchers reduce expensive noble metals for fuel cell reactions Washington State University researchers have developed a novel nanomaterial that could improve the performance and lower the costs of fuel cells by using fewer precious metals like platinum or palladium. /news/2016-08-expensive-noble-metals-fuel-cell.html Materials Science Mon, 22 Aug 2016 13:10:56 EDT news391090245
