Natural Polymer-Based Hydrogels for Glaucoma Therapy
Biopolymers have been extensively investigated in a number of medical fields, including tissue engineering and drug delivery. This is largely due to the fact that they are biodegradable within the body, and do not induce an inflammatory reaction. Polynucleotides such as nucleic acids (DNA and RNA), proteins such as polypeptides, and polyesters derived from both plants and animals are also used. When compared to synthetic polymers, naturally occurring biopolymers and their derivatives have acquired preference, and have a comprehensive range of applications in pharmaceutical as well as biomedical research. Natural biopolymers are preferred for medical applications due to their biodegradability, biostability, biocompatibility, and non-toxicity. Additionally, natural polymers have the advantage of being readily available, economically friendly, and ecofriendly. Hydrogels designed from natural polymers exhibit high potential as drug delivery systems for biomaterials to treat ocular impairments.

Natural Leaf Fiber
The use of natural fibres has rapidly increased due to their high availability, low density, and renewable capability over synthetic fibre. Natural leaf fibres are easy to extract from the plant (retting process is easy), which offers high stiffness, less energy consumption, less health risk, environment friendly, and better insulation property than the synthetic fibre-based composite. Natural leaf fibre composites have low machining wear with low cost and excellent performance in engineering applications, and hence established as superior reinforcing materials compared to other plant fibres.

Natural Fibre-Reinforced Polymer Composites
As one of the fastest-growing additive manufacturing (AM) technologies, fused deposition modelling (FDM) shows great potential in printing natural fibre-reinforced composites (NFRC). However, several challenges, such as low mechanical properties and difficulty in printing, need to be overcome. Therefore, the effort to improve the NFRC for use in AM has been accelerating in recent years.

Natural Antibacterial Additives in Bioactive Wound Dressings
Wound care is a global health issue with a financial burden of up to US $96.8 billion annually in the USA alone. Chronic non-healing wounds which show delayed and incomplete healing are especially problematic. Natural products and their derivatives have long been a significant source of pharmaceuticals against AMR. Scrutinising the data of newly approved drugs has identified plants as one of the biggest and most important sources in the development of novel antibacterial drugs.

Natural and Synthetic Polymeric Biomaterials in Wound Management
Biomaterials are at the forefront of the future, finding a variety of applications in the biomedical field, especially in wound healing, thanks to their biocompatible and biodegradable properties. Wounds spontaneously try to heal through a series of interconnected processes involving several initiators and mediators such as cytokines, macrophages, and fibroblasts. The combination of biopolymers with wound healing properties may provide opportunities to synthesize matrices that stimulate and trigger target cell responses crucial to the healing process.

Natural and Modified Cyclodextrins as Packaging Additives
Cyclodextrins (CDs) have been used by the pharmaceutical and food industries since the 1970s. Their cavities allow the accommodation of several hydrophobic molecules, leading to the formation of inclusion complexes (ICs) increasing the guest molecules’ stability, allowing their controlled release, enhancing their water solubility and biodisponibility.

Nanotechnology in Enhanced Oil Recovery
Nanotechnology is defined as a new technology for making applicable matters, systems and devices using nanosized materials, as well as new phenomena and properties at the nanoscale (1–100 nanometers) [1]. Adding certain Nanoparticles (NPs) to injection solutions can significantly benefit enhanced oil recovery (EOR), with advantages such as wettability alternation, changes in fluid properties, improving the trapped oil mobility, enhancing the consolidation of sands and decreasing the interfacial tension (IFT)

Nanocellulose-Reinforced Rubber Matrix Composites
Research and development of nanocellulose (NC) and nanocellulose-reinforced composite materials have garnered substantial interest in recent years. Rubber is a common material with a large array of applications, greatly attributed to its mechanical strength and versatility. When rubber is extracted from its natural source, it needs to undergo a compounding stage where fillers are added to reinforce the material prior to further processing. The application of nanocellulose and its variants as a substitute of conventional fillers like carbon black (CB) and silica could further reduce environmental impacts and cost as it is derived from organic biomass. Incorporation of nanocellulose as a reinforcing material could also be extended to synthetic rubber composites to carry out a similar function of improving mechanical integrity.

N,N-Dimethylacrylamide-Based Hydrogels
N,N-dimethylacrylamide produces hydrogel when polymerized with cross-linkers. Moreover, poly(N,N-dimethylacrylamide) has gotten a lot of attention as it is commonly used as the hydrophilic side of copolymers due to its unique properties and high water solubility. In addition, van der Waals interactions between N,N-dimethylacrylamide and dye molecules even more increase the applicability of DMAA hydrogels.
