The wound care market is rapidly expanding due to the development of innumerable dressings that exhibit specific healing requirements for different wound types. The use of biomaterials as suitable wound dressing material is highly advantageous due to their biocompatibility, biodegradability, and non-toxicity. Cyanobacteria have been widely explored for their potential applications in wound healing, as they are the rich source of bioactive compounds with antibacterial, antitumor, antiviral, antioxidant, and antifungal activities. In recent years this group of organisms has been widely studied due to their immense potential in biomedical applications. Although their different bioactivities can support wound healing in different ways, very few forms have proven utility as a wound-healing agent. This chapter gives an insight into the potential of cyanobacteria in wound healing. Different bioactive compounds present in variable forms of cyanobacteria and their associated activities were reported to support tissue regeneration and wound healing acceleration. As the demand for cost-effective, bioactive wound care products is ever increasing, these organisms have immense potential to be utilized for the development of bioactive wound dressings. Hence, various bioactive compounds of cyanobacteria, their associated activities, and roles in wound healing have been briefly reviewed in this chapter.

Background: Any sort of wound injury leads to skin integrity and further leads to wound formation. Millions of deaths are reported every year, which contributes to an economical hamper world widely, this accounts for 10% of death rate that insight into various diseases. Current Methodology: Rapid wound healing plays an important role in effective health care. Wound healing is a multi-factorial physiological process, which helps in the growth of new tissue to render the body with the imperative barrier from the external environment. The complexity of this phenomenon makes it prone to several abnormalities. Wound healing, as a normal biological inherent process occurs in the body, which is reaped through four highly defined programmed phases, such as hemostasis, inflammation, proliferation, and remodeling and these phases occur in the proper progression. An overview, types, and classification of wounds along with the stages of wound healing and various factors affecting wound healing have been discussed systematically. Various biopolymers are reported for developing nanofibers and microfibers in wound healing, which can be used as a therapeutic drug delivery for wound healing applications. Biopolymers are relevant for biomedical purposes owing to biodegradability, biocompatibility, and non- toxicity. Biopolymers such as polysaccharides, proteins and various gums are used for wound healing applications. Patents and future perspectives have been given in the concluding part of the manuscript. Overall, applications of biopolymers in the development of fibers and their applications in wound healing are gaining interest in researchers to develop modified biopolymers and tunable delivery systems for effective management and care of different types of wounds.

Carbon nanodots (CNDs) are more and more being exploited for various applications including biological ones. To this end, they have been thoroughly studied for their potential as antibacterial, wound healing, and bioimaging agents. In this study, we examined the sun protection properties of CNDs. Dunaliella salina was selected as a promising precursor for the synthesis of CNDs which were compared with those produced by citric acid, a widely used precursor for such materials. The CNDs were examined spectrophotometrically, and the sun protection factors were calculated. Additionally, in vitro experiments were carried out to evaluate their UV protection properties and to obtain better insight into whether CNDs are suitable to be used as filters for the development of new sunscreens. The results were conclusive that both CNDs possess favorable properties that potentiate their use for the development of sunscreens. However, the CNDs from Dunaliella salina were found to be superior to those derived from citric acid. Therefore, they can further be exploited as sun protection filters.

AbstractWound healing is an important physiological process aimed at maintaining the integrity of the skin after injury, accidentally or intentionally. Physiological wound healing involves three consecutive but overlapping phases, including hemostasis, proliferation and remodeling. Wound healing abnormalities, such as excessive wound healing (e.g. keloid) or chronic wounds (e.g. ulcers) impair normal physiological function. Many experimental studies have provided insight into wound healing. There are numerous methods that support wound healing, including popular hydrogels, vegetable oils, ultrasound and even treatment with maggots. Stem cell therapies are also very popular, but they are not safe in all cases due to having specific antibodies. In the following article, in addition to a brief overview of current healing therapies we will examine exosomal therapy, which, although new, seems to be very promising if only because of the high safety of use.Running title: Exosomes in wound healing

Abstract In volume 133 issue 4 of Clinical Science, Liu et al. showed that neutrophils release extracellular traps (NETs) in the setting of diabetes which acts as a stimulus for NLRP3 inflammasome activation in macrophages to promote IL1β-dependent exacerbation of inflammation. They also provide evidence to show that degrading NETs improves the wound healing process. These findings provide an insight into how NETs communicate with other cells in the vicinity (e.g. macrophages) to exacerbate the inflammatory response. Most importantly, they provide novel avenues to improve wound healing process such as diabetic foot ulcers (DFUs) by targeting NETs.
