Endoscopes are pretty familiar if health checkups are a routine part of one’s life. The endoscope is a long, flexible tube that houses a camera and a light source for imaging purposes.
In an article published in the journal Cancers, researchers have developed a novel portable optical polarization imaging (OPI) device for the non-invasive, rapid, and in vivo identification of basal cell carcinoma (BCC) margins.
The time it takes to manufacture fibre-optic medical devices used in healthcare has been dramatically slashed, Heriot-Watt University has announced.
A ZnO-coated optical fiber sensor for detecting a volatile organic compound biomarker for diabetes has been recently demonstrated in a study published in Sensors. The researchers used a coreless silica fiber (CSF) coupled with single-mode fiber (SMF) at both ends to synthesize the SMF-CSF-SMF structure.
A study published in Micromachines proposed a multi-sensor-based, compact, cuffless blood pressure (BP) monitoring system that combines a piezoelectric sensor array with an optical sensor to monitor the blood pressure data from the radial artery.
Researchers have created a label-free, non-invasive Raman spectroscopy method that can capture microscopic images of biological specimens promptly and accurately identify a diversity of biomolecules.
A new study published in Clinical Radiology shows a technique based on Amide Proton Transfer (APT) capable of imaging the pathophysiology of bladder cancer (BCa) causing tissue at the molecular level.
In an article published in the journal Micromachines, researchers demonstrated an electrically tunable/switchable biostable liquid crystal (LC) light shutter in biological optics through a three-step, easy-assembly, inexpensive, multichannel shutter.
A pre-proof study of Analytica Chimica Acta demonstrates the synthesis of nitrogen-doped carbon dots exhibiting green fluorescence using a one-step hydrothermal process. The as-prepared nitrogen-doped carbon dots have the potential to be used as reliable signals for tracking HS-.
A new study published in Nature Communications by the research group of Professor Wonshik Choi at the Department of Physics at Korea University demonstrates a lensless, Fourier holographic imaging fiber endoscope that performs label-free imaging of unstained biological tissues. This ultrathin fiber endoscope performs faster and provides a more accurate diagnosis than previous methods.
