Nanocarrier for selective fluorescence labeling of cancer cell and preparation method therefor

A micelle structured nanocarrier comprising an aqueous phase as an inner phase and comprising a surfactant on the surface thereof, wherein the micelle structured nanocarrier is obtained by dispersing a water-in-oil nanoemulsion comprising an oil phase ingredient, a surfactant, and an aqueous phase ingredient in water to remove the oil phase ingredient, wherein the aqueous phase comprises a cancer cell fluorescence-inducing substance and a cancer cell-targeting polysaccharide,

• wherein the cancer cell-targeting polysaccharide is entangled to each other to encapsulate the cancer cell fluorescence-inducing substance thereby forming an interpenetrating polymer network structure, wherein the cancer cell-targeting polysaccharide protrudes from a surface of the nanocarrier,
• wherein the micelle structured nanocarrier has an average size of 200 nm or less.
