Visualize surface chemistry and charge.

Communicate the distribution of H-bond donors and acceptors on the surface with clear, colour-coded graphics. See the potential causes of wettability, stickiness, flow, and electrostatic issues easily.

An icon with a magnifying glass over 3 different shapes.

Identify potential slip planes, fast.

Determine mechanical properties and guide formulation choices to support better tabletting, flow, and milling.

An icon with a piece of paper and a tick.

Evaluate particle surface interactions.

Gain insights into wettability, tabletability, flow, and sticking by understanding the interactions at the particle surface.

An arrow icon.

Visually map surface interactions.

Calculate and visualize full interaction maps (FIMs) on the surface, showing the positions a given probe is most likely to interact. Change probes to explore interaction types. For example, assess hydrophilicity with the water oxygen probe, or hydrophobicity with methyl carbon.

Determine H-bond dimensionality.

Assess hydrogen bonding dimensionality, and how discreet, 3D, or sheet hydrogen bonding impacts the mechanical properties of your product.

An icon of a checklist.

Visualize surface topology.

See surface roughness in clear, 3D graphics.

An icon with an upwards arrow over different shapes.

Quantify surface chemistry and topology.

Compare facets, particles, or structures easily by quantifying the density of H-bond donors, acceptors, aromatic bonds, unsatisfied H-bond donors, RMSD, surface area, rugosity, kurtosis, and skewness.

There are 89,365 CSD entries with 3D structural coordinates, and the habit reported as 'needle' in the CSD.


By understanding the mechanical and chemical properties of your product, potential issues in wettability, flow or sticking, tabletability, and electrostatic interactions can be identified at an early stage. Explore how the formulation and solid form impacts these properties computationally, to reduce costs and understand your product earlier.

Visual and numerical results are possible. Examine surface chemistry, topology, and interactions through interactive 3D visualizations. Quickly compare facets, particles, or structures by quantifying the density of H-bond donors, acceptors, aromatic bonds, unsatisfied H-bond donors, RMSD, surface area, rugosity, kurtosis, and skewness.

The analytical tools in CSD-Particle can be accessed through our desktop program Mercury, or via the CSD Python API. The functions are available to all academic researchers, non-academic users require a CSD-Particle licence—contact us here to request a quote, demo, or trial.
