An object of the present invention is to provide a SWCNT dispersion for bioimaging that does not aggregate, does not accumulate in a specific site when administered to a living body, does not block blood vessels such as the lung, and has low toxicity. In order to solve the above-mentioned problems, the semiconductor SWCNT dispersion liquid for bioimaging of the present invention is characterized by comprising semiconductor single-walled carbon nanotubes having an average particle diameter of less than 10 nm, and a surface coated with the semiconductor single-walled carbon nanotubes containing amphiphilic Substance dispersant. |
