When you think of gazing under a microscope, you usually image an amoeba, a human cell, or possibly a little bug on a glass slide. A new form of microscopy technique has been created, making examining the fundamental molecules that make up live creatures simpler. However, microscopes can see much more than these tiny living things. Researchers present what they call BonFIRE, or bond-selective fluorescence-detected infrared-excited spectro-microscopy.
Researchers can now examine biological processes at a previously unheard-of single-molecule level and comprehend biological systems from a molecular perspective thanks to BonFIRE, which combines two microscopy techniques into one process with increased selectivity and sensitivity. They can now view single molecules with vibrational contrast thanks to the new microscope, which is difficult to perform with conventional tools. Fluorescence microscopy is one of the techniques used in BonFIRE to view molecules and other microscopic structures by labeling them with fluorescent chemical markers so that they light when photographed.
The second method, known as vibrational microscopy, uses the inherent vibrations found in the bonds holding atoms of molecules together. In this case, infrared light is blasted at a sample that has to be photographed. The molecules of the substance vibrate as a result of that bombardment, allowing the kind of molecules to be determined.
