Technology

HOLTRA have developed the next generation of nanoparticle analysis technology. Our instrument, DAISY, provides unprecedented detail on any nanoparticle sample with the ease and efficiency of traditional nanoparticle tracking analysis (NTA). DAISY is truly a step-change in nanoparticle characterisation, providing all of the information you associate with NTA (size, concentration, polydispersity) but also, for the first time, allowing you to see inside your nanoparticles. DAISY characterises and classifies nanoparticles based on their size, internal mass distribution, refractive index, and geometry. This allows researchers to easily identify, and quantify, sub-populations, such as contaminants or aggregates, within their samples.
