Loading of each encapsulate is independently controlled while simultaneously co-encapsulating multiple components. Fluorescent dyes: B.) cyanine B.) rhodamine and C.) coumarin, at 6 different loading concentrations were printed in all possible combinations in a polystyrene 384-well and encapsulated in PLGA particles thus providing 216 different formulations. For each dye loaded, loading values obtained by pooling micro-batches of equivalent loading concentrations were significantly different from the other loading concentrations (p-value < 0.05), showing a linear trend with respect to source plate concentrations.
