NIR-II Fluorescence Imaging - Opening a New Window into Living Tissues for Preclinical Research

Taking advantage of increased penetration and contrast when imaging tissues in the NIR-II, Photon etc.’s webinar will be bridging the gap between radiology and pathology. Reaching a penetration depth of up to 3 cm in a mouse enables the high-resolution visualization of full organs and microvasculature while monitoring blood flow, metabolic rates, cellular environment, perfusion, drug biodistribution, tumour progression, heart and respiratory rates.

Cell Counting Without Slides to Reduce Waste and Cost

Until recently, cells were counted on a reusable quartz hemocytometer. With the advent of automated cell counters, disposable slides became widespread. While they're convenient for automated systems, they introduce an ongoing cost, and single-use plastic with a significant environmental footprint.

New Technique Uses Ultrasound to Noninvasively Take Optical Images

Thanks to a new breakthrough, endoscopes may no longer have to be inserted into the body—for example, under the skin or down the throat—to reach the brain, stomach, or any other organs for inspection.

	Why are you seeing this?

	Nanotechnology-based compound used to deliver hepatitis B vaccine Nanotechnology-based compounds are now being tested as a possible delivery vehicle for vaccines. A team of researchers demonstrated how the oral delivery vehicle SBA-15, one such nanotechnology-based compound can deliver an oral vaccine against hepatitis B to the immune system.

	E-FRET Microscopy for Live Cell Imaging E-FRET microscopy recently became a very popular intensity-based Fluorescence Resonance Energy Transfer (FRET) method for cell quantification. This technique reduces the photobleaching observed during the process of FRET.

	What is Reflection-contrast Microscopy? Reflection-contrast microscopy is a type of light microscopy that can be used to analyze single cells, biopsies, and other small objects. In contrary to most light microscopy techniques, reflection-contrast microscopy requires extremely thin sections, which are normally used in electron microscopy.

	First Mass Spectrometry Images Recorded Using the Matrix-Assisted Ionization in Vacuum Technique The new matrix-assisted ionization in vacuum (MAIV) technique has been used to generate mass spectrometry images for the first time. The technique’s ability to generate multiply charged ions from peptides and proteins facilitates their identification by tandem mass spectrometry.

	New Technique Allows Real-Time Microscopy at High Heat and Loading Researchers have demonstrated a technique that allows them to track microscopic changes in metals or other materials in real time even when the materials are exposed to extreme heat and loads for an extended period of time — a phenomenon known as “creep.”
