NanoImaging Services provides Molecular Microscopy imaging and analysis of samples in solution.
Sizing and Counting
- Virus Like Particles
- Liposomes and Micelles
- Titer Determination
- Empty vs. Full
- Capsulation Efficiency
Standard nanoparticle sizing methods such as dynamic light scattering (DLS) can be plagued by biases introduced by contaminants. Direct visualization of nanoparticles in solution by Molecular Microscopy methods allows exact determination of particle size, shape, and count. Read more >>
Sub-micron Aggregate Characterization
- Direct Measure
- Sub-micron to Nano Scale
- Size and Shape
- % Loss of Soluble Protein
Thorough characterization of sub-micron aggregates contained in drug products is increasingly important, but standard methods such as size exclusion chromatography (SEC) and dynamic light scattering (DLS) are indirect and fall short when it comes to the really small stuff. Visualization of sub-micron aggregate particulates in solution by Molecular Microscopy gives a direct measure of aggregation.
