AI-assisted Discovery

Discovery of novel reticular materials for carbon dioxide capture using GFlowNets
We train GFlowNets to design reticular materials such as metal organic frameworks. We identify materials outperforming all materials in the CoRE2019 reference database in terms of their simulated carbon dioxide working capacity.

Chemical space analysis and property prediction for carbon capture solvent molecules
We propose a new fingerprint and data set (ccs-98) for carbon capture solvents.

Machine Guided Discovery of Novel Carbon Capture Solvents
We combine a simple, rapid laboratory assay for CO2 absorption with a machine learning based molecular fingerprint to discover new carbon capture amines. One amine is a sugar derivative, thus potentially cheap to produce and biodegradable.

A Framework for Toxic PFAS Replacement based on GFlowNet and Chemical Foundation Model
We show that GFlowNets combined with Foundation Models can be a practical framework for discovering new small molecules that replace toxic PFAS compounds.

Symbolic Learning for Materials Discovery
We introduce a SyMDis, a symbolic learner that identifies near-optimal materials from large databases. SyMDis learns interpretable rules which achieve zero-shot generalisation to unseen datasets.

Drug Discovery

Switching Cytolytic Nanopores into Antimicrobial Fractal Ruptures by a Single Side Chain Mutation
A peptide designed using simulation forms fractal pores in the membranes of bacteria. The pores turn back to circular by modifying a single amino acid.

Accelerated antimicrobial discovery via deep generative models and molecular dynamics simulations
An autoencoder pre-trained on a dataset of antimicrobial peptides and fine-tuned to generate antimicrobial peptides. The top candidates are validated using simulation and tested in the lab. Two displayed high potency against diverse Gram-positive and Gram-negative pathogens (including multidrug-resistant Klebsiella pneumoniae) and a low propensity to induce drug resistance in Escherichia coli. Both peptides have low toxicity, as validated in vitro and in mice.

Membrane Permeability in Cyclic Peptides is Modulated by Core Conformations
Simulations reveal new guiding rules for the design of permeable cyclic peptides, focused on their core conformations.

MacroConf – dataset & workflows to assess cyclic peptide solution structures
We report a new dataset of solution structures for cyclic peptides and assess how well experimental NOE constraints are predicted by computational methods.

Membrane Binding of Antimicrobial Peptides Is Modulated by Lipid Charge Modification
Simulations reveal how certain bacteria form resistance to antibiotics through modifying the composition of the lipids in their cell walls.

Electronic coarse-grained water

Electronic coarse graining is a technique for molecular dynamics simulations which represents electrons using a quantum harmonic oscillator.

It's been described as a "soaring success" and "arguably the most powerful technique for accurate and efficient calculation of forces between molecules".
