Integrative framework for selecting gene delivery technologies in microalgae for synthetic biology

Area of Science:

• Biotechnology
• Synthetic Biology
• Microalgal Research

Background:

• Microalgae are valuable hosts for producing high-value compounds using synthetic biology.
• Existing gene delivery methods in microalgae are not fully optimized for synthetic biology applications.
• Challenges include limited cargo flexibility and engineering compatibility with current techniques.

Purpose of the Study:

• To provide a comparative analysis of gene delivery technologies for microalgal synthetic biology.
• To develop a practical framework for selecting appropriate gene delivery strategies.
• To address the need for improved delivery platforms for diverse applications and species.

Main Methods:

• Comparative analysis of conventional gene delivery technologies (agitation, microparticle bombardment, electroporation, Agrobacterium-mediated transformation).
• Evaluation of emerging non-conventional platforms (cell-penetrating peptides, metal-organic frameworks).
• Development of a selection framework based on cargo formats and species-specific characteristics.

Main Results:

• Conventional methods require enhancements in cargo flexibility and engineering compatibility for synthetic biology.
• Emerging platforms show potential but need broader species validation.
• The proposed framework organizes methods by cargo and biological context to guide selection.

Conclusions:

• Effective gene delivery is crucial for advancing microalgal synthetic biology.
• A tailored approach considering cargo and species is necessary for optimal method selection.
• Further validation of novel platforms is required for wider adoption in microalgal engineering.
