Method and system for screening nanoparticle, and nanoparticle and method of producing the same

A method for screening nanoparticles, comprising:

• dividing a nanoparticle suspension for a respective plurality of containers provided in a containment receptacle;
• performing surface modification on nanoparticles for the respective containers;
• incubating all the nanoparticle suspensions at one time under same conditions;
• preparing evaluation samples by adding a dispersion medium into each container and mixing the nanoparticles and the dispersion medium;
• and
• performing evaluation on the evaluation sample in each container by optical analysis,
• wherein the containers are arranged in a matrix, a same surface modifier is used for the containers arranged in either ones of rows or columns and different surface modifiers are used for the containers arranged in the other of the rows and columns, and same surface modification conditions other than the surface modifiers are used for the containers arranged in the other of the rows and columns, and different surface modification conditions are used for the containers arranged in the ones of rows or columns,
• wherein the surface modifiers and the surface modification conditions are adjusted on a column-by-column basis or on a row-by-row basis,
• wherein the evaluation is performed using a plurality of light emitting diodes, as a light source, arranged to face the plurality of containers, using a plurality of light receiving elements, as a light receiving unit, arranged to face the plurality of containers, and
• wherein the light emitting diodes and the light receiving elements are provided to face each other with a predetermined distance from the containment receptacle.
