Visualization　detection　methods　are　used　for　determination　of　the　concentration　of　unknown　target　by　comparing　the　color　change　in　the　intensity　or　type　of　reaction　solution　by　naked　eye.　Visualization　detection　method　has　some　advantages　such　as　simple　and　rapid　operation,　low　detection　cost,　fast　reaction　speed,　and　detecting　target　concentration　by　means　of　naked　eye.　Gold　nanomaterials　are　widely　used　in　the　construction　of　visual　biosensors　due　to　its　unique　optical　properties.　For　example,　when　changing　the　distance　or　morphology　of　the　particles,　the　plasmon　resonance　absorption　peak　of　local　surface　will　change　accordingly.　Herein,　we　reviewed　the　application　of　gold　nanomaterials　in　visualization　biosensors　for　the　detection　of　target　molecules,　summed　up　the　main　problems　of　AuNP　colormertic　methods　in　the　determination　of　actual　samples,　and　provided　an　outlook　of　the　future　of　gold　nanoparticles.　based　biosensor　in　application　development.
