A web-based software for measuring the interfacial tension of a liquid and the contact angle of a droplet, by implementing Drop Shape Analysis (ADSA).
Based on the fitting of the Young-Laplace equation to a liquid droplet image data, DropUI calculates the contact angle of the droplet, as well as the surface tension of the liquid. The mathematical framework of the method as well as the validation against other, well-established, ADSA packages (ramé-hart DROPimage Advanced and ImageJ plugins DropAnalysis & Pendant_Drop) are described in reference .
- Automated liquid surface tracking by using a modified version of the threshold method.
- Automated detection of droplet type (sessile or pendant).
- Interfacial tension and Young's contact angle measurement by fitting a theoretical droplet profile (Young-Laplace equation) to the experimental image. The solution of the Young-Laplace equation can be performed either by numerical integration or with a computationally much more efficient method by using an artificial neural network.
- DropUI is the successor of DropToolKit. No installation is now required. Just register and use the web-based interface.
