“…As can be seen from Figure 4, the hydrogel was found to be thermally more stable in comparison to its major constitutes. The cross‐linking in polymer network seems to be responsible for enhanced thermal stability of hydrogel 2 …”

“…However, the potential of natural materials is limited by their relatively low mechanical strength and fast degradation. These drawbacks can be improved by chemically cross‐linking the polymers using multi‐component network approach 2 . The multicomponent networks are formed by crosslinking two different polymers by covalent linkages using a suitable cross‐linker with at least two reactive ends.…”

A multi‐component, fluorescent hydrogel of chitosan and gelatin using maleic acid as a cross‐linking agent was fabricated with improved mechanical and thermal properties. The FTIR spectroscopy and SEM studies confirmed the formation of a cross‐linked and porous hydrogel. The XPS studies confirmed the presence of rich functionalities over the surface of hydrogel. The hybrid hydrogel possessed strong blue emission band centered at 438 nm when excited with an absorption band centered at 384 nm. The fluorescent hydrogel was tested for selective detection of different heavy metal ions including Cr (VI) in the aqueous solution. The strong complexation among the functional groups of hydrogel and metal ions led to the quenching of hydrogel's fluorescence. The fluorescence of hydrogel was quenched significantly in the presence of Cr (VI) ions in comparison to the other heavy metal ions. The fluorescence‐quenching efficiency displayed a linear response to the Cr (VI) concentration in the range of 1–14 nM with a lower detection limit of 0.12 nM. Embraced with good sensitivity and selectivity for Cr (VI) ions, the solid hydrogel with stable fluorescent properties holds a great potential in chemical sensing applications.

“…Actually, the grafting of cellulose with synthetic polymers through the use of ATRP, other CRP techniques, or free radical polymerization is being considered in the scientific community as an effective route to generate new materials for many different applications. Ions removal from aqueous solutions, dyes degradation, stimuli-responsive hydrogels fabrication or aqueous aggregates generation [1][2][3][4][5], are just a few examples of such kinds of applications (ref. [1] contains a comprehensive list of cellulose modification techniques and applications).…”

“…Generally, biopolymeric nanoparticles have used in the field of foods encapsulation and drug delivery studies due to the biodegradability, biocompatibility, and low toxicity properties. Alginate [19], chitosan [20], carboxymethyl cellulose/gelatin [21], Senegal gum [22], guar gum [23], xanthan gum [24], Senna tora gum [25], and locust bean gum (LBG) [26] are natural biopolymers employed in industrial processes [24]. Locust bean gum is a neutral polysaccharide and has a mannose backbone with single side chain galactose units [25][26][27].…”

In this study, PEGylated locust bean gum-rosin glycerol ester polymeric nanoparticles (PEG-LBG/RE PNPs) were synthesized by using simple ultrasonic irradiation method. The nanoparticles were characterized by using Fouriertransform infrared spectroscopy (FTIR) and scanning transmission electron microscopy (STEM). The viscosity behaviors of nanoparticles were studied in different conditions (pH, sonication time, and salt). The experimental results were calculated by Huggins, Kraemer, Tanglertpaibul-Rao, and Higiro models to understand the colloidal stability, the miscibility mechanism, and coefficients of nanoparticles. The results confirmed that the homogenous distribution of nanostructure was related to sonication time (30 min) and the presence of NaOH salt. With the addition of NaOH, the nanosystem based on ionotropic gelation technique was made more homogeneous. The results made us think that nanoparticles can be a good candidate for drug delivery systems in biomedical and pharmaceutical applications.
