Several coronavirus disease 2019 (COVID-19) vaccines require multiple doses for long-lasting immunity. However, a new study published in the journal Biomacromolecules has developed a promising ...

The development of highly secure but simple and inexpensive encryption technology for the prevention of data leaks and forgeries is decidedly challenging. A research team has now introduced a 'double ...

Scientists in Sweden have created a new class of non-antibiotic hydrogel capable of fighting multidrug-resistant (MDR) bacterial infections by enhancing the skin’s natural immune defense.

Designing soft materials such as gels and elastomers involves striking the right balance between chosen chemicals, ratios, and arrangements of monomers to produce a material with the desired ...

Electrically tunable ionic hydrogels use small voltages to switch friction at metal contacts between high-friction and ultra-low-friction states, enabling voltage-programmed grip, release and motion ...

Scientists has found that firmer, lower water content hydrogels limit bacterial growth, with implications for designing antibacterial coatings, infection models, and advanced medical materials.
