Chemistry Dissertations

The sensitivity of biological studies performed between 190 and 650 nm is greatly reduced due to the autofluorescence of biomolecules and impurities in this region. Therefore, the enhanced signal-to-noise ratios encountered at longer wavelengths makes biological analysis within the near infrared (NIR) region from 650 nm to 1100 nm far more advantageous. This dissertation describes the noncovalent binding interactions of near-infrared (NIR) carbocyanine dyes with human serum albumin (HSA) and poly-L-lysine (PLL) using UV-Vis/NIR absorption spectroscopy, emission spectroscopy, circular dichroism (CD), and fluorescence detected circular dichroism (FDCD). The optical spectroscopy methods used in this work are described in detail in …
