In　this　work,　molecularly　imprinted　electrospun　chromogenic　membrane(MIP-ECM)　was　synthesized　using　P-Hydroxybenzene　propanoic　acid　as　imitate　template　molecule　and　Poly　(vinyl　alcohol)(PVA)　as　substrate.　Ninhydrin　is　used　as　chromogenic　agent　for　visualizing　detection　of　target　molecule　L-tyrosine(Tyr).　The　results　showed　that　molecularly　imprinted　membrane　exhibited　selectivity　and　specific　adsorption　capacity　for　L-tyrosine.　The　influences　of　environmental　factors,　such　as　reaction　temperature,　the　amount　of　ninhydrin　and　elution　time,　on　chromogenic　properties　were　examined　by　SEM　and　optical　microscope.　Gray　value　analysis　is　proceeded　by　software　Image　J.　Due　to　the　facilitate　preparation　and　intuitive　visualization,　the　proposed　method　was　a　promising　candidate　for　selective　recognition　of　bio-generated　acid　and　amino　molecules.
