When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially ...

Scientists have developed the first fluorescent nanosensor capable of detecting indole-3-propionic acid (IPA) - a metabolite ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

Optical fibers were proposed for long-distance communications about six decades ago. Soon, researchers discovered that optical fibers could also be ...

Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

A COVID-19 sensor developed at Johns Hopkins University could revolutionize virus testing by adding accuracy and speed to a process that frustrated many during the pandemic. In a new study published ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...
