One mode of an optical inspection apparatus according to the present invention is an optical inspection apparatus for optically inspecting an object, the optical inspection apparatus including: a biasing section () configured to apply, to a group of objects (A) on a stage, a force for moving the group of objects away with respect to the stage (); a catching section () including an adhesion portion () to which an object in the group of objects moved from the stage adheres; and an analysis section () configured to optically analyze the object caught by the catching section. This makes it possible to efficiently and satisfactorily perform optical analysis of individual microplastics by eliminating manual work of picking up the microplastics one by one.

Provided is a skin external preparation including a drug and nanometer-size molecular assemblies. The molecular assemblies contain an amphiphilic block copolymer having a hydrophilic block chain including a sarcosine-derived structural unit and a hydrophobic block chain including a hydroxy acid-derived structural unit. The skin external preparation according to the present invention may reduce skin irritation caused by the drug, be very safe, and have excellent pharmacological effects, even when a drug that is generally difficult to be transdermally administered due to its strong skin irritation is contained therein.
