1. A shoe inspection apparatus for detecting hidden or dangerous substances, the shoe inspection apparatus comprising:
an inspection unit configured to accommodate an inspection subject;
a transmission unit configured to emit electromagnetic waves toward the inspection subject accommodated in the inspection unit;
a reception unit configured to receive the electromagnetic wave reflected from the inspection subject;
an injection unit configured to inject a fluid toward a bottom part of the inspection subject accommodated in the inspection unit;
a suction unit configured to suction a material separated from the bottom part of the inspection subject together with the fluid; and
an analysis unit configured to analyze a component of the material introduced into the suction unit and the electromagnetic wave received by the reception unit,
wherein the injection unit comprises a first injection unit and a second injection unit,
wherein the suction unit comprises a first suction unit and a second suction unit,
wherein the first injection unit and the first suction unit spaced apart in a first direction,
wherein the second injection unit and the second suction unit spaced apart in a second direction that is intersecting with the first direction,
wherein the inspection unit disposed between the first injection unit and the first suction unit, and disposed between the second injection unit and the second suction unit,
wherein microfluidic channels are provided on an upper surface of the inspection unit,
wherein the microfluidic channels comprise trenches defined on the upper surface of the inspection unit respectively, and
wherein the trenches extend in the first direction.
