Application of bacteriophages in sensor development.

Area of Science:

• Biotechnology
• Biosensor Technology
• Molecular Diagnostics

Background:

• Traditional antibody-based immunoassays face limitations in cost, production, and animal use.
• Bacteriophages (phages) are virus particles that infect bacteria, offering unique biological properties.
• Phages are robust, naturally abundant, human-safe, and easily produced, making them ideal for bioassays.

Purpose of the Study:

• To provide a critical review of recent advancements in phage-based bioassays and biosensors.
• To highlight the advantages of using bacteriophages over traditional immunoassay components.
• To survey various interrogation techniques employed in phage-based biosensor development.

Main Methods:

• Review of scientific literature on phage-based bioassays and biosensors published in recent years.
• Analysis of different phage conjugation and genetic engineering strategies.
• Categorization of biosensors based on interrogation methods (colorimetric, enzymatic, fluorescence, SPR, QCM, etc.).

Main Results:

• Phage-based bioassays demonstrate excellent robustness, sensitivity, and selectivity.
• Phages can be easily conjugated or genetically engineered for specific targets.
• Diverse transduction techniques are successfully integrated with phage-based platforms.
• Phage production is economical and avoids animal use, unlike antibody production.

Conclusions:

• Bacteriophage-based bioassays represent a significant advancement in biosensing technology.
• Their ease of production, robustness, and sensitivity make them a superior alternative to conventional immunoassays.
• Continued development promises wider applications in diagnostics and detection.
