This　work　is　an　exploration　into　visualizing　measurement　of　putrescine　specific　adsorption　by　photographing　colorized　molecule　imprinting　chromogenic　hydrogel.　Membranes　are　prepared　with　imitate　templates　1,4-butylene　glycol,　adipic　acid　or　succinic　acid,　respectively　and　ninhydrin　is　used　as　chromogenic　agent　for　target　molecule　putrescine.　The　adsorbing　concentration　on　MIP　is　reflected　in　the　form　of　visible　violet-colored　stain　differed　in　shape　and　shade,　which　are　recorded　by　hyper　spectral　camera　and　proceeded　into　intuitive　3D　isohypse　surfaces　plot.　By　quantifying　the　height　of　surface　peaks,　imprinting　efficiency　is　estimated　in　accordance　with　polyvinyl　alcohol　concentration　and　crosslinking　degree.　The　imprinting　efficiency　of　three　imitate　molecule　templates　is　also　discussed.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
