What sets Spectradyne’s technology apart?
Spectradyne’s F-MRPS outperforms Dynamic Light Scattering (DLS), Nanoparticle Tracking Analysis (NTA), and Nanoscale Flow Cytometry (nanoFCM).
A unique perspective
Microfluidic Resistive Pulse Sensing (MRPS) is a fundamentally different way to measure particles than optical methods (e.g., DLS, NTA or nanoFCM)
In our ARC Particle Analyzer, MRPS is combined with quantitative single-particle fluorescence (F-MRPS) to deliver the most direct measurements of particle size, concentration and payload than currently available
For LNP applications, the ARC enables direct quantification of encapsulated payload on a single-particle basis, unlike bulk fluorescence techniques such as RiboGreen or Qubit assay. Along with configurable, multiparameter excitation and collection optics, the ARC allows for a wide range of experimental opportunities. Gather data on multiple key attributes into your sample simultaneously, without the hassle of time-consuming assays or difficult calibration and alignment processes.
