A prototype formulation based on layer-by-layer (LbL) nano-matrix was developed to increase bioavailability of kaempferol with improved retention in bone marrow to achieve enhanced bone formation. The layer-by-layer nano-matrix was prepared by sequential adsorption of biocompatible polyelectrolytes over the preformed
