“…(2) The method of radiation preparation of hydrogels can be prepared by using radiation of different energies (such as gamma rays, electron beams, etc. ), so different radiation sources and energies can be selected according to the parameters needed to control the morphology, structure, and properties of the hydrogels [139]. (3) There is no need to add chemical reagents in the preparation process of radiation-prepared hydrogels, which avoids the problems of chemical reaction instability and composition impurities, thus improving the controllability of production.…”

Hydrogels are materials consisting of a network of hydrophilic polymers. Due to their good biocompatibility and hydrophilicity, they are widely used in biomedicine, food safety, environmental protection, agriculture, and other fields. This paper summarizes the typical complex materials of photocatalysts, photosensitizers, and hydrogels, as week as their antibacterial activities and the basic mechanisms of photothermal and photodynamic effects. In addition, the application of hydrogel-based photoresponsive materials in microbial inactivation is discussed, including the challenges faced in their application. The advantages of photosensitive antibacterial complex hydrogels are highlighted, and their application and research progress in various fields are introduced in detail.

“…Various groups of them were used especially polyesters, including poly(L-lactic acid) (PLLA), and cellulose derivatives. PLLA and cellulose derivatives e. g., ethyl cellulose (EC) and cellulose acetate butyrate (CAB) are wellknown biopolymers used for the preparation of polymer capsules [10][11][12][13]. Because they are natural polymers that are readily available, inexpensive, nontoxic, biologically friendly, and can be biodegradable [14][15][16][17].…”

Moringa oil (MO) contains various bioactive components and pharmacology. It is attractive to use as a raw ingredient in various products. However, there are limitations on its direct utilization, especially MO's instability and hastening the active ingredient's degradation from external environmental factors, including temperature, humidity, oxidation, light, and heat. To solve these problems, in this work, microencapsulation of MO using different biopolymers as cellulose acetate butyrate (CAB), ethyl cellulose (EC), and poly(L-lactic acid) (PLLA) were carried out by a simple solvent evaporation technique. The prepared polymer microcapsule suspensions were highly colloidal stable for all types of biopolymers and ratios. The spherical biopolymer capsules were formed to a micrometer size after solvent evaporation under all conditions. However, when the microcapsules were dried, aggregation was found with the polymer microcapsules at a ratio of PLLA to MO of 50:50 for all three types of polymers, possibly due to the low amount of polymer to completely encapsulate all of MO. When polymer contents increased to 70%, the dried spherical polymer microcapsules were smoothly produced. Using 70% polymers, the PLLA microcapsule surface was smoother than the polymer microcapsules prepared by CAB and EC which exhibited the dent or hole on the outer surface. Micrometer size, spherical polymer capsules with a core-shell morphology were fabricated. Due to the higher hydrophilicity of the polymer than the MO, the polymer moves outward, forming a strong shell around the MO. Then, all three biopolymers can be used for the microencapsulation of MO at a suitable polymer to MO ratio. However, using PLLA at a ratio of PLLA to MO of 70:30 presented the highest encapsulation efficiency (74.08%), which may be due to its high molecular weight. Because of the non-toxicity and biodegradability of biopolymers, the fabricated microcapsules would be well applied in cosmetic products.
