Fascinating how the lotus leaf model has been applied in a number of fields – here, its remarkable hydrophobicity features in the sustained drug release field. One face of this group’s dosage form adheres to the gastrointestinal mucosa. The exposed face emulates the lotus leaf’s surface micro-/nano-structure, as well as being fluoropolymer-coated, to repel GI contents and help maintain attachment for the long term. Good results so far + a thought that more specific adherence sites may be targeted.
