“…45 The increased antibacterial effect of adding essential oil or bioactive compounds on films against Gram-positive and Gram-negative bacteria has been extensively studied. 17,45,46 Positive controls rifampicin, vancomycin, and chloramphenicol were tested against the wound isolate, and the results are shown in Table 2. Rifampicin showed the highest inhibition (29 mm) compared to chloramphenicol (19 mm) and vancomycin (15 mm).…”

“…Their chemical nature determines the enhancement of physical and mechanical properties of the resulting film. [15][16][17] The use of synthetic chemicals such as polyvinyl alcohol and polyvinylpyrrolidone based films had developed resistance in microbes, and also was not applicable for a longer usage in the environment due to non degradable properties. The use of plastic-based products has become part of our life and led to the rapid emergence of the plastic industry in the past several decades.…”

Eucalyptus oil ( Eucalyptus globulus ) nanoemulsion was formulated using low-and high-energy emulsification methods. Development of nanoemulsion was optimized for system parameters such as emulsifier type, emulsifier concentration, and emulsification methods to obtain a lower droplet size with greater stability. The minimized droplet diameter was achieved using the high-energy method of ultrasonication. Tween 80 was more effective in reducing droplet size and emulsion appearance when compared to Tween 20. Stable nanoemulsion was formulated with Tween 80 as a surfactant, and the particle size was found to be 9.4 nm (1:2 v/v). The eucalyptus oil nanoemulsion was impregnated into chitosan (1%) as a biopolymer in varying concentrations. Further, the film was characterized by moisture content, microscopic study, X-ray diffraction, and Fourier transform infrared spectroscopy. Also, the film with and without nanoemulsion was evaluated against Staphylococcus aureus . The nanoemulsion-impregnated chitosan film showed higher antibacterial activity than chitosan film. These results support the inclusion of nanoemulsion-impregnated chitosan film in wound management studies.

“…24,25 It has also been shown that the chitosan films made using lactic acid exhibit improved mechanical properties making them promising candidates for fabricating scaffolds for tissue engineering. [26][27][28] In this work, we have prepared conducting biocompatible hydrogels using chitosan and lactic acid as the matrix.…”

Composites of graphene in a chitosan-lactic acid matrix were prepared to create conductive hydrogels that are processable, exhibit tunable swelling properties and show excellent biocompatibility. The addition of graphene to the polymer matrix also resulted in significant improvements to the mechanical strength of the hydrogels, with the addition of just 3 wt% graphene resulting in tensile strengths increasing by over 200%. The composites could be easily processed into three-dimensional scaffolds with finely controlled dimensions using additive fabrication techniques and fibroblast cells demonstrate good adhesion and growth on their surfaces. These chitosan-graphene composites show great promise for use as conducting substrates for the growth of electro-responsive cells in tissue engineering.
