Mainly extracted from citrus peel and apple pomace, PEC represents a heterogeneous group of acidic biomacromolecules and, because of its gelling characteristics, as well as bioadhesivity, biocompatibility and non toxicity properties, it is also a promising biopolymer able to act as a drug delivering vehicle. PEC is, conversely, an anionic polysaccharide at pH higher than 4.6, widely occurs in fruits and vegetables and is generally used in food and pharmaceutical industries as gelling and thickening agent. Moreover, CH-based edible films and coatings allow extending and preserving shelf life of different foods. Due to its non toxic, biodegradable and biocompatible properties, CH is extensively used in the biomedical area as wound healing material and for sustained release of drugs. CH is a copolymer consisting of β-(1–4)-2-acetamido-D-glucose and β-(1–4)-2-amino-D-glucose units with the latter usually exceeding 60%. ĬH is a cationic biopolymer under pH 6.0 and derives from the N-deacetylation of chitin, the natural polysaccharide responsible for the hardness of the crustacean shells. In this respect, the utilization of charged polysaccharides like chitosan (CH) or pectin (PEC) appears to be one of the most interesting way in manufacturing of biodegradable new materials. Temperature range extension option to 120✬.Different natural biopolymers are becoming the issue of an expanding number of studies reporting their potential applications in food, pharmaceutical and cosmetic technologies, as well as in tissues engineering.Optical filter option to improve measurements with fluorescent sample.Alternative laser, 50mW at 532nm for samples incompatible with the standard 633nm laser.Optional flow mode capability to enable use as a GPC / SEC size detector.Automation of measurements using an autotitrator option.

In addition, a microrheology option is available for measuring sample viscosity and viscoelastic properties, as well as a Protein Measurement option for protein mobility measurements. Using Non-Invasive Backscatter optics (NIBS) it has significantly better performance than systems using 90 degree scattering optics. The ZSP also incorporates a zeta potential analyzer that uses electrophoretic light scattering for particles, molecules and surfaces, and a molecular weight analyzer using static light scattering. The Georgia Tech Zetasizer Nano ZS, located in the Georgia Tech Biocleanroom, is a high performance two angle particle and molecular size analyzer for the enhanced detection of aggregates and measurement of small or dilute samples, and samples at very low or high concentration using dynamic light scattering with ‘NIBS’ optics.
