Overcoming human bias in peptide discovery

As reported in Nature Communications, researchers have developed s fully automated computational search engine for peptide discovery.

Scientific Achievement

Typically, peptide discovery research yields fewer than ten candidates per study and is subject to human bias. A fully autonomous computational search engine has been developed to reveal peptide sequences with high potential for self-assembly.

Significance and Impact

This AI expert has the potential to accelerate discovery of self-assembling peptides with applications ranging from tissue engineering and surface coating to catalysis and sensing.

Research Details

  • The AI expert developed in this work combines Monte Carlo tree search, molecular dynamics simulations, and a peptide-structure-based scoring function.
  • It was demonstrated to efficiently search spaces with 8,000 tripeptides and 6,600 pentapeptides.

Work was performed, in part, at the Center for Nanoscale Materials (CNM).
