Ebook "Hydrogels: Biological properties and applications" have had a rapid, exponential evolution in the last decades. Starting from one of the first applications of hydrogels in surgery, polyvinylalcohol crosslinked with formaldehyde under the trade name of Ivalon, we passed through PolyHema hydrogels as contact lens materials, hydrophilic polyurethanes (HPU), biodegradable hydrogels for both reconstructive surgery and pharmaceutical delivery systems, and finally more recently, one decade old, the thermoreversible and transient network hydrogels.

We describe the synthesis, characterization and catalytic properties of a series of hybrid materials composed of inorganic plasmonic mono- and bimetallic nanoparticles supported on organic bio-based hydrogel beads. The bimetallic materials showed a localized surface plasmon resonance in the visible region, with a maximum light absorption correlated to the metal composition of the alloyed systems.

This study reports the preparation of poly(sodium-4-styrene sulfonate) (PSS) treated bentonite and clinoptilolite to prevent the agglomeration and sedimentation of these inorganic fillers during the preparation of hydrogel. For this purpose PSS treated fillers were prepared by using various techniques (dip and dry, hydrothermal, one-step ball milling and ultrasonication methods). The most suitable technique for preparing these PSS treated inorganic fillers (abbreviated as BP-dip and CP-dip) was the dip and dry method.

A new class of injectable, biocompatible and biodegradable hydrogel is reported. This hydrogel is derived from N-succinyl chitosan (SCS) mixed with water-soluble dialdehyde starch (DAS) without using a conventional chemical crosslinker. The hybrid hydrogel is formed owing to the Schiff’s base reaction between amine groups of SCS and dialdehyde groups of DAS to form ACH‚NA group. SCS, DAS, and SCS–DAS hybrid hydrogels were synthesized and then characterized by FTIR analysis spectroscopy.

In the study, injectable chitosan–4 hydroxyphenylacectamide acid (CHPA) and gelatin– tyramine (GTA)–based hydrogels were enzymatically prepared, in which could encapsulate biphasic calcium phosphate nanoparticles (BCP NPs) for enhancing bone regeneration. The in situ formation of hydrogel composite was varied from 35 to 80 seconds depending on concentration of H2O2.
