In recent years, Total Internal Reflection Fluorescence (TIRF) microscopy has become an important method for studying molecular interactions near the cell surface. To accommodate the trend of the ...

The FDA has issued new rules related to the prescribing of opioid painkillers. The rules apply to transmucosal immediate-release fentanyl, or TIRF, drugs. The drugs contain fentanyl, a powerful opioid ...

Some doctors have been prescribing opioids to Medicare Part D drug plan beneficiaries to relieve their cancer pain -- even though they didn't actually have cancer, according to a report from the ...

A mouse fibroblast cell imaged on a metasurface made of gold nanoparticles under a total internal reflection fluorescence (TIRF) microscope exhibits enhanced and confined emission from light-emitting ...

Total internal reflection fluorescence (TIRF) microscopy is a method that resolves molecular events specifically at or near the cell surface (see How It Works). Major microscope manufacturers, ...

Stick a soda straw into a glass of water, and from the side, the straw will appear to bend at the interface between air and water. That effect is caused by the different refractive indexes of the air ...
