Antimicrobial activity screening using a luminescent bacterial strain (Pseudomonas aeruginosa H1001).

Main Results:

The SPOT technique allows for fast, cost-efficient, and parallel synthesis of peptide arrays.
Synthesized peptides are readily cleaved and suitable for direct screening.
High-sensitivity screening achieved using engineered bacteria, correlating luminescence with antimicrobial activity.

Conclusions:

The SPOT technique is a versatile platform for peptide array synthesis and antimicrobial drug discovery.
This approach supports medium- to high-throughput screening for novel antimicrobial peptides.
The method aids in the development of new drugs to combat multidrug-resistant bacterial infections.
