IISc Develops STring Representation Of Nanopore Geometry(STRONG)

November 22, 2024

Recent advancements in nanopore research have emerged from the Indian Institute of Science (IISc). Researchers have developed a novel language called STRONG, which describes nanopore shapes and structures using a sequence of characters. The publication appeared in the Journal of the American Chemical Society.

STRONG Language Overview

STRONG stands for STring Representation Of Nanopore Geometry. It assigns different letters to various atom arrangements. Each letter signifies a specific atom configuration at the nanopore’s edge. For instance, ‘F’ denotes a fully bonded atom, while ‘C’ represents a corner atom bonded to two others. These configurations are crucial for determining nanopore properties.

Data Reduction and Similarity Identification

STRONG aids in identifying similar nanopores with the same edge atoms. This capability remains effective even if the nanopores are rotated or reflected. Consequently, it reduces the data volume required for property prediction.

Machine Learning Integration

The STRONG language facilitates training machine learning models. Neural networks, akin to ChatGPT, can interpret STRONG sequences. These models, commonly used in Natural Language Processing, manage long sequences and possess memory functions. Unlike traditional programming, neural networks learn from data rather than follow explicit instructions.

Training the Neural Network

Researchers trained the neural network using data from known nanopore structures. This data included various properties, such as energy levels and gas transport barriers. By learning from this information, the neural network approximates functions to estimate nanopore properties based on STRONG descriptions.

This innovative approach opens avenues for reverse engineering. Scientists can design nanopores with tailored properties. Such advancements hold promise for applications in gas separation and other fields. The STRONG language represents step forward in nanopore research and machine learning integration.
