Recent advances in cellulose nanocrystals-based antimicrobial agents

Area of Science:

• Materials Science
• Nanotechnology
• Biochemistry

Background:

• Cellulose nanocrystals (CNCs) are increasingly explored as nanoscale antimicrobial agents due to their renewable origin and favorable properties.
• Their large surface area and hydroxyl groups facilitate surface modification for enhanced functionality.
• CNCs also serve as stable supports for other antimicrobial agents.

Purpose of the Study:

• To review recent advancements in modified cellulose nanocrystal (CNC)-based hybrid materials for antimicrobial applications.
• To focus on the design, synthesis, and application of CNC-inorganic and CNC-organic hybrids.
• To discuss the antimicrobial mechanisms of these hybrid materials.

Main Methods:

• Review of literature on CNC-inorganic hybrid materials (e.g., Ag, Zn nanoparticles, metal oxides).
• Review of literature on CNC-organic hybrid materials (e.g., polymers, chitosan).
• Analysis of synthesis strategies and application-specific performance.

Main Results:

• CNCs can be effectively combined with inorganic (Ag, Zn, metal oxides) and organic (polymers, chitosan) agents to create potent antimicrobial materials.
• These hybrid materials show promise in food packaging, additive manufacturing, biomedical fields, and water purification.
• Surface modification of CNCs enhances their antimicrobial efficacy and allows for tailored material design.

Conclusions:

• Modified CNCs offer a sustainable and versatile platform for developing advanced antimicrobial solutions.
• Hybrid CNC materials demonstrate significant potential across various industrial and biomedical sectors.
• Further research into their modes of action and large-scale production is warranted.
