Protein-based wound dressings have garnered increasing interest in recent years owing to their distinct physical, chemical, and biological characteristics. The intricate molecular composition of proteins gives rise to unique characteristics, such as exceptional biocompatibility, biodegradability, and responsiveness, which contribute to the promotion of wound healing. Wound healing is an intricate and ongoing process influenced by multiple causes, and it consists of four distinct phases. Various treatments have been developed to repair different types of skin wounds, thanks to advancements in medical technology and the recognition of the diverse nature of wounds. This review has literature reviewed within the last 3-5 years-the recent progress and development of protein in wound dressings and the fundamental properties of an ideal wound dressing. Herein, the recent strides in protein-based state-of-the-art wound dressing emphasize the significant challenges and summarize future perspectives for wound healing applications.
In orthopaedic clinical applications, creating biocomposite bone substitutes to take the place of autologous bone transplants is still difficult. Studies have demonstrated for decades that poly (lactic-co-glycolic acid) [PLGA], a common polymer, has many benefits that make it a strong contender for bone replacement. These include biodegradability, good mechanical qualities, and the ability to induce new bone production. Although calcium-based materials are frequently used as bone fillers in bone implantation, the efficiency of ceramic materials containing calcium may be hampered by a number of issues, including low microporosity and quick rates of degradation. In order to overcome these obstacles, scientists are investigating ways to improve implant performance by combining PLGA with other materials, especially in terms of encouraging improved connections with nearby bone cells. An overview of the chemical properties of different PLGA-based scaffold composites, as well as the benefits and drawbacks of PLGA-Calcium implants in tissue engineering applications, are the goals of this review. It also highlights the possible advantages and consequences of using PLGA in 3D printing technology to improve bone tissue engineering clinical outcomes.
