A solution of phenol red is used as a pH indicator, often in cell culture. Its color exhibits a gradual transition from yellow ( λ max = 443 nm) to red (λ max = 570 nm) over the pH range 6.8 to 8.2.

11, 12, 13 This wavelength region is potentially attractive from the standpoint of measuring concentrations of water and lipid because absorption features of these chromophores are more Infrared absorption spectroscopy of lipid layers was performed by combining optics and scanning probe microscopy. This experimental approach enables sub-diffraction IR imaging with a spatial resolution on the nanometer scale of 1, 2-dioleoyl-sn-glycero-3-phosphocholine lipid layers. As seen in Fig. 3, the simulated plaque could be clearly distinguished using the wavelength bands at 1150–1290 nm and 1650–1790 nm, which include the lipid absorption peak wavelengths. These bands are suitable for MSI of atherosclerotic plaque because of strong absorption by the lipid and only weak effect by absorption of water.

This experimental approach enables sub-diffraction IR imaging with a spatial resolution on the nanometer scale of 1, 2-dioleoyl-sn-glycero-3-phosphocholine lipid layers. An early study showed that atheroma could be identi- fied using photoacoustic methods by exploiting the strong pre- ferential absorption that lipid-rich plaques exhibit in the wavelength range 420 to 530 nm17—the source of contrast being the presence of carotenoids, which are related to the pro- cess of lipid accumulation. color.

A solution of phenol red is used as a pH indicator, often in cell culture. Its color exhibits a gradual transition from yellow ( λ max = 443 nm) to red (λ max = 570 nm) over the pH range 6.8 to 8.2. Above pH 8.2, phenol red turns a bright pink ( fuchsia) color. Tracing Lysozyme-Lipid Interactions with Long-Wavelength Squaraine Dyes. Journal of Fluorescence, 2006. Paavo Kinnunen ATR-FTIR can be used to study these systems in a number of different ways. One such way to monitor the adsorption rate of these lipid vesicles from a bulk solution to a solid interface.

3.2. FA standards • Absorbance at 260 nm Nucleic acids absorb UV light at 260 nm due to the aromatic base moieties within their structure. Purines (thymine, cytosine and uracil) and pyrimidines (adenine and guanine) both have peak absorbances at 260 nm, thus making it the standard for quantitating nucleic acid samples.
