See how they grow: Monitoring single bacteria without a microscope

(PhysOrg.com) -- With an invention that can be made from some of the same parts used in CD players, University of Michigan researchers have developed a way to measure the growth and drug susceptibility of individual bacterial ...

Cell-detection system promising for medical research, diagnostics

(Phys.org) —Researchers are developing a system that uses tiny magnetic beads to quickly detect rare types of cancer cells circulating in a patient's blood, an advance that could help medical doctors diagnose cancer earlier ...

Self-assembly and chains of rotating magnetic particles

Dr. Park and colleagues report on a new biosensing protocol based on monitoring changes in optical transmittance of a solution containing self-assembled chains of functionalized magnetic beads being rotated by an external ...

New technology for bioseparation

Separating target molecules in biological samples is a critical part of diagnosing and detecting diseases. Usually the target and probe molecules are mixed and then separated in batch processes that require multiple pipetting, ...

Novel, low-cost metal-forming process using a magnetic field

European scientists developed a novel foundry process using moulds formed by 'binding' metallic particles with application of a magnetic field. The process produced high-quality, complex parts at a very competitive cost.

Nanostructured sensors power novel cancer detection system

(Phys.org) -- Using a sensor made of densely packed carbon nanotubes coated with gold nanoparticles, a researcher team headed by James Rusling of the University of Connecticut has developed a low-cost microfluidic device ...
