Gold　thin　films　have　attracted　a　growing　number　attention　because　of　their　advantages　such　as　easy　preparation,　conveniently　subsequent　modifications,　good　chemical　stability,　high　electrical　conductivity　and　low　cytotoxicity.　The　preparation　of　continuous　metal　layer　on　capillary　has　become　a　classic　leading　step　in　the　field　of　analytical　chemistry.　In　recent　years,　researchers　have　established　a　variety　of　methods　to　prepare　gold　thin　films,　which　has　been　applied　in　many　fields.　This　paper　reviews　the　preparation　methods　of　gold　thin　films　based　on　capillary,　and　its　application　in　electrochemical　sensing　analysis,　mainly　discussing　the　technical　characteristics　and　research　status　of　electroless　deposition,　electrochemical　deposition　and　physical　vapor　deposition.　In　addition,　the　development　prospects　of　gold　plating　on　capillary　are　also　prospected.
