Nanoparticles colloids are of particular interest in modern science. They are actively used in electronics, sensorics, for improvement of solar elements properties, for drug delivery, in disinfectors, etc [1]. The range of applications of nanoparticles is constantly expanding and most likely will be expanding in the coming decades. One of the relevant directions of studies in this field is the synthesis of nanoparticles of different materials with specified properties. It is, obviously, important to define nanoparticles properties when developing protocols for the synthesis of nanoparticles with specified parameters. Also, when conducting experiments with nanoparticles, it is necessary to know their parameters. There are many experimental techniques for defining the nanoparticles properties, e.g. dynamic light scattering, transmission electron microscopy, zeta-potential measurements, optical spectroscopy, surface plasmon resonance spectroscopy [2]. Obtained experimental data must be processed in order to define parameters of nanoparticles, or they need to be compared in order to define the similarity or difference in properties of several samples.
In the work we study various methods of processing of data of dynamic light scattering of nanoparticles colloids and implement them in the web application. The application allows to import the results of experiments on dynamic light scattering of nanoparticles colloids, process them, and output the graphs with the samples properties, and *.txt file with the description of evaluated properties and conclusion on similarity of samples (if applicable). User may choose the properties of graphs, and methods and criteria for comparison of samples, and also read brief description of applied methods with relevant references. Processing of other types of data will be implemented in further studies.
We are grateful to Iu. Mukha and N. Vityuk from O.O.Chuiko Institute of Surface Chemistry of NAS of Ukraine for fruitful discussions and useful comments.
