“…These species could contribute to the reduction of metal cations, leading to formation of various metal NPs such as AuNPs and AgNPs in aqueous solutions [23,24]. With the use of PiLC, we have successfully synthesized a wide range of nanocomposites containing metal based NPs, such as AuNP/CNT [25], AuNP/GO [26], Fe3O4/PINIAM [27], AuNP/PEDOT:PSS [28], and PVA hydrogel composites containing AuNP, AgNP or AuAg alloyed NPs [29]. One of the unique features of the PiLC synthetic approach is its ability to create highly charged NP surfaces within minutes, resulting in highly dispersed / stable NPs without the need for reductants, surfactants or ligand chemistry.…”

Room temperature atmospheric pressure microplasma (APM) was deployed for the first time for the in situ synthesis of anti-bacterial silver nanoparticle/chitosan (AgNP/CS) nanocomposites. The plasma induced liquid chemistry plays a role in the in situ formation of AgNP, the size distribution of which depends on the silver salt precursor concentration. The microplasma process has also simultaneously tailored the physical properties of the composites, through molecular chain scission and formation of physically crosslinked polymer network. The formation of AgNP within the in situ modified chitosan has led to nanocomposites with overall improved mechanical properties and better stability in simulated body fluid. Our plasma synthesized AgNP/CS nanocomposites also demonstrate effective antibacterial properties against E. coli and S. aureus bacterial strains, showing their promise in potential antimicrobial applications.

“…NPs such as Fe 3 O 4 can be synthesized without yielding negligible effects in the chemical bonding of PNIPAm hydrogel. This results in a thermoreversible hydrogel with magnetic behavior [176]. Antibacterial NPs such as gold and silver may also be processed in hydrogels where polymers such as PVA functions as a capping agent to prevent agglomeration.…”

The use of materials to restore or replace the functions of damaged body parts has been proven historically. Any material can be considered as a biomaterial as long as it performs its biological function and does not cause adverse effects to the host. With the increasing demands for biofunctionality, biomaterials nowadays may not only encompass inertness but also specialized utility towards the target biological application. A hydrogel is a biomaterial with a 3D network made of hydrophilic polymers. It is regarded as one of the earliest biomaterials developed for human use. The preparation of hydrogel is often attributed to the polymerization of monomers or crosslinking of hydrophilic polymers to achieve the desired ability to hold large amounts of aqueous solvents and biological fluids. The generation of hydrogels, however, is shifting towards developing hydrogels through the aid of enabling technologies. This review provides the evolution of hydrogels and the different approaches considered for hydrogel preparation. Further, this review presents the plasma process as an enabling technology for tailoring hydrogel properties. The mechanism of plasma-assisted treatment during hydrogel synthesis and the current use of the plasma-treated hydrogels are also discussed.

“…Besides free‐standing NPs in gas phase or colloidal NPs dispersed in solution, nanocomposites or nanohybrids composed of metal NPs and substrate materials including CNT, graphene nanosheets, polymers, and hydrogels can be prepared using microplasma‐assisted liquid‐phase synthesis at room temperature and ambient pressure. Recent works include AuNP/CNT, AuNP/graphene oxide (GO), AuNP/poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate, and Fe 3 O 4 NP/poly( N ‐isopropylacrylamide) hydrogels . For example, Au NPs can be directly synthesized from Au containing salt precursor by chemical reduction and simultaneously deposited on CNT surfaces to form a nanohybrid‐like structure during the microplasma‐assisted liquid‐phase synthesis (Figure e).…”
