Environment-responsive hydrogel actuators have attracted tremendous attention due to their intriguing properties. Gamma radiation has been considered as a green cross-linking process for hydrogel synthesis, as toxic cross-linking agents and initiators were not required. In this work, chitosan/agar/P(N-isopropyl acrylamide-co-acrylamide) (CS/agar/P(NIPAM-co-AM)) and CS/agar/Montmorillonite (MMT)/PNIPAM temperature-sensitive hydrogel bilayers were synthesized via gamma radiation at room temperature. The mechanical properties and temperature sensitivity of hydrogels under different agar content and irradiation doses were explored. The enhancement of the mechanical properties of the composite hydrogel can be attributed to the presence of agar and MMT. Due to the different temperature sensitivities provided by the two layers of hydrogel, they can move autonomously and act as a flexible gripper as the temperature changes. Thanks to the antibacterial properties of the hydrogel, their storage time and service life may be improved. The as prepared hydrogel bilayers have potential applications in control devices, soft robots, artificial muscles and other fields.

PEG-based dually crosslinked injectable hydrogels have been developed through extremely simple chemistry which avoids use of small molecular weight crosslinker, formation of by-products and involved low heat change. The hydrogels are useful for wound healing and soft tissue regeneration.

Wound healing entails a sequence of complex biological processes, which is a protective function of the body that focuses on a quick recovery. Reducing wound healing time is crucial in a wound as it lowers the chance of infection and decreases complications and costs. Papaya extract was obtained by a maceration method. It contains papain enzyme, flavonoid, saponin, and alkaloid, which act as an anti-inflammatory, astringent substance, vasodilator, antioxidant, analgesic, with antifungal, and antibacterial properties, and increase the collagen synthesis. This study aimed to assess the effect of Carica papaya extract application toward incised wound healing process in mice (Mus musculus) clinically and histologically. This experimental laboratory study was performed using 24 mice weighing between 30 and 40 grams and 12 and 14 weeks of age as experimental animals. Each group was incised along 5 mm at the labial gingiva under both of mandible anterior teeth with a depth reaching alveolar bone. Papaya extract was applied topically in the morning and evening for 14 days. The clinical result was obtained by assessing the length of wound closure measured every day for 14 days. Based on the statistic test result, it showed that the papaya extract has a significant effect (p≤0.05) toward the healing process of an incised oral wound in mice. Histologically at day 14, 75% concentration papaya extract showed perfect epithelial layer and fibrillation.

Diabetic foot ulcer (DFU) is a chronic wound frequently delayed from severe infection. Wound dressing provides an essential barrier between the ulcer and the external environment. This review aimed to analyse the effectiveness of antibacterial collagen-based dressing for DFU treatment in a clinical setting. An electronic search in four databases, namely, Scopus, PubMed, Ovid MEDLINE(R), and ISI Web of Science, was performed to obtain relevant articles published within the last ten years. The published studies were included if they reported evidence of (1) collagen-based antibacterial dressing or (2) wound healing for diabetic ulcers, and (3) were written in English. Both randomised and non-randomised clinical trials were included. The search for relevant clinical studies (n) identified eight related references discussing the effectiveness of collagen-based antibacterial wound dressings for DFU comprising collagen impregnated with polyhexamethylene biguanide (n = 2), gentamicin (n = 3), combined-cellulose and silver (n = 1), gentian violet/methylene blue mixed (n = 1), and silver (n = 1). The clinical data were limited by small sample sizes and multiple aetiologies of chronic wounds. The evidence was not robust enough for a conclusive statement, although most of the studies reported positive outcomes for the use of collagen dressings loaded with antibacterial properties for DFU wound healing. This study emphasises the importance of having standardised clinical trials, larger sample sizes, and accurate reporting for reliable statistical evidence confirming DFU treatment efficiency.
