“…Because of the enormous potential of cellulose materials, it is of great interest to develop novel functional cellulose‐based biomaterials by introducing antibacterial/antimicrobial activities through the functionalization and/or incorporation of antibacterial/antimicrobial agents. For instance, antimicrobial nanocellulose‐based materials have been obtained by the incorporation of N ‐halamine and nanocurcumin into the cellulose network and by the chemical grafting of aminoalkyl groups, 2‐benzyl‐4‐chlorophenol, l ‐cysteine, and diclofenac onto the surface of the cellulose backbone.…”

Nanocellulose materials have undergone rapid development in recent years as promising biomedical materials because of their excellent physical and biological properties, in particular their biocompatibility, biodegradability, and low cytotoxicity. Recently, a significant amount of research has been directed toward the fabrication of advanced cellulose nanofibers with different morphologies and functional properties. These nanocellulose fibers are widely applied in medical implants, tissue engineering, drug delivery, wound-healing, cardiovascular applications, and other medical applications. In this review, we reflect on recent advancements in the design and fabrication of advanced nanocellulose-based biomaterials (cellulose nanocrystals, bacterial nanocellulose, and cellulose nanofibrils) that are promising for biomedical applications and discuss material requirements for each application, along with the challenges that the materials might face. Finally, we give an overview on future directions of nanocellulose-based materials in the biomedical field.

“…Recently, hemp as an antibacterial agent has been attracting more and more attention . Hemp fiber has been confirmed with excellent antibacterial activity, which leads hemp fiber to be a good material for functional textiles . However, antibacterial performance of hemp hurd has never been systematically investigated, although it is repeatedly announced that hemp hurd also has similar property .…”

Hemp (Cannabis sativa L.) is an eco-friendly and multifunctional plant. Hemp hurd is a by-product of hemp plant during hemp fiber separation. Although hemp hurd is repeatedly announced owing antibacterial activity, it has never been systematically investigated and reported. In this study, the antibacterial activity of hemp hurd powder against Escherichia coli is investigated. This article reveals antibacterial activity of hemp hurd where hemp hurd powder inhibits the growth of E. coli. Meanwhile, the selfcontamination (forming during retting process) inside hemp hurd has dramatic impact on the antibacterial performance. To achieve better antibacterial activity, hemp hurd was heat treated to eliminate self-contaminations. The impact of the particle sizes and heat treatment on the antibacterial effectiveness was evaluated.

“…Cassano et al (2013) prepared material via esterification of hemp with 2-benzyl-4-chlorophenol, a germicidal agent, which was covalently coupled to cellulose backbone of hydrophilic fibers by a heterogeneous synthesis, to produce a functionalized biopolymer with a satisfactory degree of substitution. Its antibacterial activity in inhibiting S. aureus and P. aeruginosa growth in Petri dishes suggested that this biomaterial possesses an excellent in vitro antibacterial activity and so it can be efficiently employed in biomedical fields to ensure a protection against contaminations.…”

Intervention against pathogenic bacteria using natural plant material has a long history. Plant materials also have been widely used as fillers and/or reinforcers in polymer composites. Some natural fibre plants, such as hemp, are regarded to possess antibacterial activity against a wide range of pathogenic bacteria. Innovative applications can be explored if they are incorporated in polymer composites. This review aims to compile the relevant investigations on antibacterial activity of hemp and other fibre plants such as jute, flax, kenaf, sisal, and bamboo. The antibacterial character might be contributed from cannabinoids, alkaloids, other bioactive compounds, or phenolic compounds of lignin. This review is intended to encourage utilization of hemp and other natural fibre plants in value-added diversified products. Some potential applications are also discussed.
