Fiber Optic Sensors that Dissolve Within the Human Body

As a first ever attempt, scientists have developed sensing elements called fiber Bragg gratings within optical fibers, formed to dissolve absolutely within the body. The bioresorbable fiber Bragg gratings can be adopted for in-body observation of bone fracture healing and for secure investigation of sensitive organs, for example, brain.

WPI Researchers Developing Miniaturized Fiber Optical Tweezers to Detect Cancer at Early Stages

In a paper published in Nature Scientific Reports, a team of researchers at Worcester Polytechnic Institute (WPI) has demonstrated how a device that uses beams of light to grip and manipulate tiny objects, including individual cells, can be miniaturized, opening the door to creating portable devices small enough to be inserted into the bloodstream to trap individual cancer cells and diagnose cancer in its earliest stages.

UV Microscope Serves as Powerful Diagnostic Tool in Patient Care and Medical Research

A microscope that uses ultraviolet (UV) light to illuminate samples allows pathologists to assess high-resolution images of fresh tissue samples, including biopsies, for various diseases within a matter of minutes, without damaging the tissue or requiring lengthy preparation of traditional slides.
