NDKmol

NDKmol is a sophisticated molecular viewer tailored for Android users, designed to visualize the intricate three-dimensional structures of various biomolecules. This powerful tool is adept at portraying proteins, nucleic acids, and small molecules with high accuracy. Users can enjoy a wide array of representation styles, including ribbon, trace, stick, sphere, and line models, allowing for customization based on scientific needs or preferences.

One of the key features of this application is its support for symmetry operations. Biologists and chemists can easily display biological assemblies and crystal packing, offering an in-depth look into molecular structures as they exist in nature. The app allows for effortless searching and downloading of structures from two major databases, RCSB PDB and NCBI PubChem, ensuring that the most recent and relevant molecular data are readily available.

Equipped with advanced features, the application offers different modes of coloring molecules, smoothing of beta-sheets for enhanced visualization, along with crystallography tools including the display of unit cells and crystal packing. These capabilities further its value for professionals engaged in the chemical and biological sciences.

Interactivity is a core element, facilitating easy model manipulation through simple finger gestures. Rotate, translate, and zoom functions operate smoothly to provide an intuitive experience. Precision control is at users' fingertips with two-finger gestures to zoom or translate the molecule.

For user convenience, upon launching, it automatically loads an example molecule. This can be replaced by placing a PDB file in the designated directory on the device's SD card or by downloading directly from supported databases. Offering functionalities that rival desktop-based viewers, NDKmol is an essential resource for anyone looking to explore and analyze molecular structures through their Android device.
