“…Significant research has been carried out on polyamide microcapsules starting from a range of monomers (aliphatic or aromatic, bifunctional or polyfunctional, etc.) [ 24 , 27 , 31 , 33 , 36 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ]. The effect of process variables such as ratio of monomers, type and concentration of the emulsifier, emulsification method, and time on the final ΡA MCs properties, especially the size, shell integrity, permeability along with release profiles and mechanisms, has been investigated.…”
