Fluorescence imaging can track vitamin C in the body

Vitamin C is best known as a nutrient. In high enough doses, however, vitamin C also shows potential against many cancers, according to recent studies. To successfully develop vitamin C (chemically named ascorbic acid) as a medication, it is crucial to probe its concentration in the body, thus ensuring safe and effective doses.

Choosing The Correct Camera for Fluorescence Microscopy

It is important to select the proper camera for fluorescence microscopy which has high sensitivity and low noise, to avoid photo bleaching your sample. A monochrome camera is also preferred for fluorescence imaging because it does not have a color filter pattern superimposed over the image sensor. Since the microscope’s filter wheel selects which wavelength makes its way to the sensor, a monochrome camera allows equal signal detection on all pixels and increases the overall sensitivity of the camera.

Solar retinopathy or sun damage to the eyes – a case report

A case report titled, “Acute Solar Retinopathy Imaged With Adaptive Optics, Optical Coherence Tomography Angiography, and En Face Optical Coherence Tomography”, appeared in the journal JAMA Ophthalmology, where the authors describe the damage caused by the sun’s rays to the eyes of a woman who viewed the recent solar eclipse without adequate eye protection. This type of eye damage is termed acute solar retinopathy.
