Active Delivery Studies

Fluorescence Microscopy

If you want to show that your actives deposit onto the hair surface or penetrate deeper into the fiber you may consider doing some active delivery studies.


TRI Princeton have experience in labelling hair actives and visualizing penetration using a fluorescence microscope.  Fluorescence microscopy is ideal for actives that are difficult to visualize directly with spectroscopy imaging, such as peptides and proteins.  TRI also has access to a confocal fluorescence microscope for higher quality imaging.
