Carbohydrate and protein based biopolymeric nanoparticles: Current status and biotechnological applications.

Wide sustainability and reusability of biomacromolecules such as carbohydrates and proteins-based biopolymers pave the way for providing maximal importance in the field of generating biopolymeric nanoparticles. As compared to synthetic nanomaterials, carbohydrate and protein based biopolymeric nanomaterials offer unique advantages that include antibacterial, biocompatible, immunogenicity, and biodegradable properties. Additionally, they have the significant property of more size distribution.

Photoacoustic measurement of refractive index of dye solutions and myoglobin for biosensing applications.

Current methods of determining the refractive index of chemicals and materials, such as ellipsometry and reflectometry, are limited by their inability to analyze highly absorbing or highly transparent materials, as well as the required prior knowledge of the sample thickness and estimated refractive index. Here, we present a method of determining the refractive index of solutions using the photoacoustic effect. We show that a photoacoustic refractometer can analyze highly absorbing dye samples to within 0.
