DNA nano-devices perform bio-analytical chemistry inside live cells

Researchers developed a DNA nanosensor that can measure the physiological concentration of chloride with a high degree of accuracy.

Microneedle patch delivers localized cancer immunotherapy to melanoma

Biomedical engineering researchers have developed a technique that uses a patch embedded with microneedles to deliver cancer immunotherapy treatment directly to the site of melanoma skin cancer.

Nanocage surfaces get makeover in room temperature

Nanocrystals morph via anion exchange by exploiting crystal structure.

Newly discovered organic nanowires leave manmade technologies in their dust

A newly discovered microbial protein fiber transports charges at rates high enough to be applied in manmade nanotechnologies.

New open source software for high resolution microscopy

Researchers have developed a new open source software solution for ultra-high resolution fluorescence microscopy that can process such raw data quickly and efficiently.

Moving microswimmers with tiny swirling flows

Scientists have discovered a way to use a microscopic, swirling flow to rapidly clear a circle of tiny bacteria or swimming robots.

Reserchers roll out new method for making the invisible brushes that repel dirt

Polymer crystal 'turf' improves nanobrush-making process.

Graphene nanoribbons: it's all about the edges

Researchers have for the first time succeeded in producing graphene nanoribbons with perfect zigzag edges from molecules. Electrons on these zigzag edges exhibit different (and coupled) rotational directions ('spin').
