To measure pressure distribution in high Knudsen number regimes, we have adopted a pressure sensitive paint (PSP) technique, because the PSP works as a so-called "molecular sensor". However, application of the PSP to micro-devices is very difficult because the conventional PSP is too thick owing to the use of polymer binder. Moreover, they have not sufficient spatial resolution for pressure measurement of micro-flows because of the aggregation of luminescent molecules in polymer binders. In our past work, we have adopted Langmuir-Blodgett (LB) technique to fabricate pressure sensitive molecular films (PSMFs) using Pd(II) Mesoporphyrin IX (PdMP) to resolve the problems of ordinary PSPs mentioned above. However the luminescent intensity of PSMF is low, leading to low SN ratio because the amount of luminescent molecules in the layer is small. In this study, we have applied localized surface plasmon resonance to increase luminescent intensity of PSMF and have tested PSMFs to evaluate the feasibility of the pressure measurement around the micro-devices. A PSMF with nanometer order thickness and high spatial resolution is suitable for analyses of micro-flow.
