Simple Method Measures How Long Bacteria Can Wait Out Antibiotics
Sleepy Bacteria Evolve to Resist Antibiotics
Antibiotic resistance is a major and growing problem worldwide. According to the World Health Organization, antibiotic resistance is rising to dangerously high levels in all parts of the world, and new resistance mechanisms are emerging and spreading globally, threatening our ability to treat common infectious diseases. But how these bacterial resistance mechanisms occur, and whether…
Ultra-Precise Chip-Scale Sensor Finds Nanoscale Changes
Chip scale high precision measurements of physical quantities such as temperature, pressure and refractive index have become common with nanophotonics and nanoplasmonics resonance cavities. As excellent transducers to convert small variations in the local refractive index into measurable spectral shifts, resonance cavities are being used extensively in a variety of disciplines ranging from bio-sensing and…
