Laser-Assisted Bioprinting of Neurons

A team at Concordia University in Montreal have developed a technique called Laser-Induced Side Transfer (LIST) that allows for bioprinting of neurons. Low energy laser pulses are directed at a capillary containing a cell-laden bioink, resulting in microbubbles that eject a microjet of the ink onto the substrate below. The technique appears to be fairly […]

Chip Detects Antibiotics in Exhaled Breath

Researchers at the University of Freiburg in Germany have developed a chip that can measure antibiotic levels in breath, potentially paving the way for rapid point-of-care antibiotic testing. Attaining the correct levels of antibiotics in the body is crucial to effectively treating infections and avoiding drug side-effects or the development of antibiotic-resistant bacteria. The chip […]

Antimicrobial Coating Prevents Infections Around Ortho Implants

A group at Duke University engineered an antibiotic delivery system to make the surfaces of orthopedic implants resistant to bacterial infiltration. The technique involves spraying or painting a combination of hydrophilic and hydrophobic polymers, mixed with an antibiotic of choice, onto the surface of the implant. A UV light is then used to cure the […]
