Smart packaging uses good viruses to kill food bacteria

May 06, 2026 Phage-infused alginate packaging helps fight biofilms, limit bacterial growth, preserve freshness, and support safer, greener shelf life. (Nanowerk News) Food packaging does more than hold our food; it protects it from contamination, preserves freshness, and keeps us safe. But some bacteria are relentless, forming biofilms that cling...

Wafer-level meta-aspheric lens enables ultracompact wide-angle near-infrared imaging

May 06, 2026 Researchers developed a wafer-level meta-aspheric lens combining 101.5-degree field of view, 3.39 mm thickness, and high imaging quality for AR glasses and smartphones. (Nanowerk News) Researchers at Hunan University and their collaborators have developed a meta-aspheric lens that combines wide-angle near-infrared imaging, an ultrathin profile, and high...

Plasmonic nanomachines use light to create motion

May 06, 2026 Plasmonic nanomachines use light-generated gradients to create local force, offering a design framework for controlled motion at micro- and nanoscale dimensions. (Nanowerk Spotlight) A machine seems simple at human scale: supply energy, generate force, produce motion. That intuition breaks down when the moving object becomes smaller than...

With large DNA fragment assembly, scientists can design microbes that produce countless complex products

May 06, 2026 Scientists can now build and combine large DNA pieces, letting microbes like yeast and bacteria become efficient cell factories for medicines, fuels and chemicals. (Nanowerk News) A review in Quantitative Biology ("Advances in large DNA fragment assembly for microbial cell factory engineering") demonstrates that scientists can now...

A comprehensive theory for nematoelasticity

May 05, 2026 Theorists address an experimental paradox by developing a general theory uniting a kind of order known as electronic nematicity with a crystal's elasticity. (Nanowerk News) Electronic nematicity is a phase of some crystalline solids in which electrons’ collective properties, such as charge or spin densities, organize themselves...
