Polylysine (CAS 25104-18-1) is a naturally occurring biopolymer and a homopolymer of L-lysine, a natural amino acid. It is known for its positive charge density, biodegradability, and biocompatibility, making it an attractive material for various applications in the biomedical field and beyond .
As a food additive, polylysine and its derivatives, such as ε-poly-L-lysine, have gained significant attention due to their antimicrobial properties. They exhibit broad-spectrum antimicrobial activity against a range of microorganisms, including bacteria, yeasts, and molds. This makes them useful as natural food preservatives to extend the shelf life of food products .
In the biomedical sector, polylysine is utilized in drug and gene delivery systems due to its ability to bind and transport therapeutic agents effectively. It can be functionalized to improve its performance, making it a promising carrier for targeted drug delivery . Additionally, polylysine is used in the development of bio-adhesives for tissue repair and as a component in wound healing and tissue engineering applications .
Polylysine's cationic nature allows it to interact with negatively charged surfaces, which is beneficial for coating and immobilization purposes. It is used to coat surfaces in cell culture applications to enhance cell adhesion and growth . Furthermore, polylysine can be used in the formulation of biosensors, as it can immobilize enzymes and other biologically active molecules onto surfaces
