title: Fabrication of gradient mesostructures by Langmuir-Blodgett rotating transfer.
abstract: In this letter, we present a simple yet novel method, Langmuir-Blodgett (LB) rotating transfer, to achieve a continuous gradient mesostructure in a well-ordered fashion over large areas. A mixed monolayer of phospholipid and dye is chosen as a model system to test the feasibility of LB rotating transfer to fabricate continuous gradient structures, which is confirmed by the simulation and experimental results. The technique presented here to obtain gradient structures is low-cost and high-throughput and can be extended to other systems of LB patterning.
