Bacteriophage Capsid Modification by Genetic and Chemical Methods.

Area of Science:

• Biotechnology
• Virology
• Materials Science

Background:

• Bacteriophages (phages) are viruses with natural specificity for bacteria, making them valuable for biotechnological applications.
• Phage capsids can be functionalized for diverse uses, but native surface groups limit specificity and consistency.
• Existing modification methods face challenges with permanence and targeted conjugation.

Purpose of the Study:

• To review and compare genetic and chemical bacteriophage capsid modification techniques.
• To identify strengths and weaknesses of current modification strategies.
• To highlight future research directions for advancing phage-based technologies.

Main Methods:

• Genetic modification: Altering phage genomes or capsid genes to incorporate specific amino acids or peptides.
• Chemical modification: Reacting native capsid functional groups with activated conjugates.
• Review of existing literature on phage modification methodologies.

Main Results:

• Both genetic and chemical methods offer distinct advantages for specific applications.
• Genetic approaches allow for precise, stable, and specific conjugation.
• Chemical methods provide versatility but can face challenges with specificity and coverage.

Conclusions:

• Advanced bacteriophage capsid modification is crucial for developing novel biosensors, vaccines, therapeutics, and nanocarriers.
• Further research is needed to optimize both genetic and chemical strategies for robust phage-based applications.
• Tailored phage modifications promise significant advancements in medicine and agriculture.
