Dental restoratives are a perfect surface for the prolific growth of bacterial biofilm cultures. S. gordonii in particular is a pioneering colonizer of tooth surfaces, allowing other bacteria to ...

A laboratory-grown Pseudomonas aeruginosa biofilm. 3D images were acquired by an advanced light sheet theta microscopy system (ClearScope) developed in Columbia’s Department of Biological Sciences.

Bacteria are traditionally imagined as single-cell organisms, spread out sparsely over surfaces or suspended in liquids, but in many environments the true bacterial mode of growth is in sticky ...

Confocal laser scanning microscopy of Salmonella wet biofilm (WSB) and dry surface biofilm (DSB). The DSB displays a distinctive "sandwich-like" vertical structure, as revealed in the cross-sectional ...

A bacterial cell settles onto a nondescript surface. It is plump, healthy and functioning as it should. Nothing appears amiss ...

Scientists at the Department of Energy's Oak Ridge National Laboratory have reimagined the capabilities of atomic force microscopy, or AFM, transforming it from a tool for imaging nanoscale features ...

Electron microscopy has become a vital tool in structural biology, enabling researchers to visualize biological macromolecules at near-atomic resolution. Recent advances have transformed it from a low ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

Key Points Years of studying natural surfaces-like the nanopillared wings of cicadas and dragonflies-have revealed a powerful ...

Many bacteria form an antibiotic-resistant slime. Research detailing that slime's structure could help lead to new treatments. Many bacteria form an antibiotic-resistant slime. Research detailing that ...
