The process of examining and comprehending the characteristics and behaviour of particles is known as particle characterisation. Particles can vary in size, shape, content, and other attributes. They can be solid, liquid, or gaseous. Particle characterisation aims to offer comprehensive details about these particles so that their physical, chemical, and biological characteristics may be better understood.

Many scientific and industrial sectors, including materials research, medicines, environmental science, nanotechnology, and chemical engineering, depend on the ability to characterise particles. Researchers and engineers can better understand particle interactions, behaviour, and effects on numerous systems and processes by researching particles.

Measurement and analysis of important factors are necessary for particle characterisation, following are a few examples:

  • Particle Size Analysis:

Understanding a particle's behaviour, responsiveness, and performance depends on its size. Different methods, including microscopy, laser diffraction, sedimentation, or dynamic light scattering, can be used to analyse particle size.

  • Particle Shape:

Particle shapes affect their physical and chemical characteristics, as well as how they behave in various situations. Methods like microscopy, image analysis, or automated shape characterization algorithms are used to describe particle shapes.

  • Particle Composition:

Determining the components, compounds, or functional groups that are present in a particle by analysing its chemical makeup. Particle composition is ascertained using methods like spectroscopy, elemental analysis, or mass spectrometry.

  • Surface Properties:

Particles' surface properties, such as their surface area, porosity, charge, or wettability, have a big impact on how well they interact with other particles and substances. Common surface analysis methods include zeta potential measurement, contact angle measurement, and BET (Brunauer-Emmett-Teller) analysis.

  • Particle Concentration:

Determining the number of particles or their concentration in a sample is necessary to comprehend their abundance and dispersion. Particle concentrations are measured using techniques like microscope counting, flow cytometry, or particle counters.

Scientists and engineers may fully grasp the characteristics, behaviour, and interactions of particles by characterising them using these and other pertinent factors. In several sectors and research domains, this information facilitates the creation and optimisation of materials, processes, and technologies.

How are Artificial Intelligence and Machine Learning Used in Particle Characterization

Particle characterisation is increasingly using artificial intelligence (AI) and machine learning (ML) approaches to examine and comprehend complicated particle systems. Here are some examples of applications of AI and ML in this area:

Images of particles obtained by microscopy methods may be analysed using AI and ML algorithms. ML models may be taught to recognise and categorise various types of particles based on their size, shape, colour, and other properties by being trained on a collection of labelled photos. This makes particle recognition and characterisation automatic and precise.

  • Particle Tracking:

Monitoring the behaviour and movement of particles in a system is essential to comprehending their characteristics. Particles may be tracked in real-time or from recorded films using AI and ML approaches. Researchers can glean useful statistics from the trajectory data, including particle velocity, diffusion coefficients, and interactions between particles.

  • Feature Extraction:

To describe the characteristics of particle data, ML systems may extract pertinent features. Examples of characteristics that ML models may learn to extract from particle photos or other types of particle data include statistical measurements, fractal dimensions, and texture properties. Then, these characteristics can be utilised to categorise particles or foretell their physicochemical characteristics.

  • Data analysis and modelling:

AI and ML may be used to analyse sizable datasets of measurements of particle characterization, including particle size distribution, composition, and surface characteristics. ML models can spot patterns, correlations, and trends in the data that conventional analytic techniques can find difficult to spot. These models can also be employed to develop particle behaviour prediction models or to enhance particle production procedures.

  • Simulation and modelling:

Particle simulation models can be more accurate and effective when AI and ML approaches are used with them. To calibrate and improve simulation models, machine learning (ML) algorithms may learn from experimental data. This allows for more accurate predictions of particle behaviour under varied circumstances. When it comes to complicated particle systems, where analytical solutions are less common, this is very helpful.

  • Real-time decision-making:

Real-time decision-making and control systems for particle characterisation procedures can be aided by AI and ML. ML models may offer insights and suggestions for process optimisation, quality control, and anomaly detection by continually observing and examining particle data. This may result in increased particle characterisation efficiency, dependability, and product consistency.

Overall, automated analysis, pattern identification, prediction, and process optimisation are made possible by AI and ML approaches, which provide strong tools for particle characterisation. They promote improvements in several disciplines, including materials research, medicines, environmental science, and nanotechnology, and they help us understand particle systems better.

Which are the Newly Developed Technologies for Particle Characterization Based on Machine Learning?

In recent years, several newly created machine learning (ML)-based particle characterisation methods have appeared. To improve particle analysis and offer more precise and effective characterisation, these technologies make use of ML algorithms. Here are some illustrations:

Convolutional neural networks (CNNs) are a popular deep learning approach for image analysis in particle characterisation. These models are capable of automatically identifying and categorising particles based on their characteristics in microscope pictures. They can also obtain exact measurements of particle size, shape, and other characteristics, obviating the need for manual examination.

  • Reinforcement Learning for Particle Tracking:

Algorithms for reinforcement learning (RL) have been used to solve particle tracking issues. Real-time learning (RL) models develop their tracking techniques over time by interacting with a tracking environment and learning to track particles. Particularly in complicated systems or under difficult imaging conditions, this method can increase the precision and effectiveness of particle tracking algorithms.

  • Generative Adversarial Networks for Data Augmentation (GANs):

For data augmentation in particle characterisation, ML models of the GAN type are utilised. To increase the training dataset for ML models, GANs may create synthetic particle pictures that mimic genuine particle images. This enables ML algorithms for particle analysis tasks to become more robust and broader.

  • Transfer Learning for Generalisation:

Using limited data, transfer learning is a technique that enables ML models to use information from one domain to perform better in another. Transfer learning can be used in particle characterisation to adapt previously learned models from related disciplines or well-characterised particle systems to novel and understudied particle types or experimental configurations. This makes it possible to analyse novel particle systems more quickly and accurately.

  • Active Learning for Data Labelling:

This method actively chooses the most instructive samples for annotation, which optimises the data labelling process. Active learning techniques can prioritise which particles in particle characterisation need to be manually labelled to train ML models more efficiently. This keeps model performance high while reducing the total labelling effort.

With unprecedented opportunities for automation, precision, and optimisation in the study of complex particle systems, these technologies demonstrate the promise of machine learning (ML) in particle characterisation.
