NANOSPACER 

TECHNOLOGY

OPEN-SOURCE Tracking software (FIJI)

NTA data handling has never been more transparent. Use freely available tracking software to get most out of your data. Trackmate (FIJI) and Trajectory classifier  TraJ (FIJI) plugins allow to analyze your NTA sizing videos free of charge. Analyze EVs, NPs on your own laptop whenever, wherever you like.
