ε-Polylysine Hydrochloride in the Biomedical Field: Potential Applications and Analysis

I. Antimicrobial and Preservative Effects

·Broad-spectrum Antimicrobial Activity: ε-Polylysine hydrochloride exhibits significant inhibitory effects on a wide range of microorganisms, including Gram-positive and Gram-negative bacteria, yeasts, and molds. Its broad-spectrum antimicrobial activity makes it valuable in the biomedical field, particularly in products requiring protection against microbial contamination.

·Synergistic Enhancement: When used in combination with other antimicrobial agents,ε-polylysine hydrochloride can produce a synergistic effect, enhancing the overall antimicrobial efficacy. This makes it more effective in protecting the stability and safety of products in complex microbial environments.

II. Drug Carrier and Controlled Release Systems

·Drug Carrier: ε-Polylysine hydrochloride is rich in cations and has strong electrostatic interactions with anionic drug molecules. Thus, it can be used as a drug carrier to achieve targeted delivery and controlled release of drugs, thereby improving bioavailability and therapeutic effects.

·Controlled Release Systems: With good hydrophilicity and biodegradability, ε-polylysine hydrochloride can be used to construct drug-controlled release systems. These systems can gradually release drugs in the body, prolonging their action, reducing the frequency of administration, and minimizing side effects.

III. Biomedical Materials

·Tissue Engineering and Repair: As a biodegradable polymer, ε-polylysine hydrochloride can gradually degrade in the body and release its constituent amino acids. It can be used in tissue engineering and biological repair fields. For example, it can serve as a cell scaffold material, promoting cell adhesion and growth, and accelerating tissue repair and regeneration.

·Antimicrobial Coating: Coating medical devices or implants with ε-polylysine hydrochloride can form an antimicrobial layer, effectively preventing microbial contamination and infection. This is significant for enhancing the safety and efficacy of medical devices.

IV. Other Applications

·Gene Therapy: In cell transfection, ε-polylysine hydrochloride can form complexes with DNA, achieving efficient gene transfection. This suggests potential applications in gene therapy.

·Nutritional Supplement: ε-Polylysine hydrochloride is a direct polymer of lysine and can decompose into lysine in the human body. Thus, it can also be used as a nutritional supplement, helping to provide the lysine needed by the body and promoting protein synthesis and metabolism.

ε-Polylysine hydrochloride has broad application potential and significant research value in the biomedical field. With further research and technological advancements, it is expected to play an increasingly important role in the future biomedical sector. However, attention must be paid to its safety and efficacy in practical applications to ensure it can truly benefit human health.
