The use of high-resolution bright-field microscopy is essential for cellular-scale biological research, but this technique has limitations due to low image contrast. Using dyes on the sample can ...
IN a recent study of the NHCO group in polyamides and proteins 1 it was found that the peak extinction value of the infra-red fundamental NH absorption band at 3,300 cm. −1 for nylon 6 depended on the ...
Proteins containing the appropriate amino acids are absorbent to light on the UV-spectrum, specifically light that has peak wavelengths of 260 – 280 nanometers (nm). This makes it simple to analyze ...
