In a Raman spectroscopic system: a sample cell in which a sample is filled or through which the sample flows down, where the sample has fluidity and contains one or more materials being to be measured, and having an electrophoretic feature or being conditioned in advance so as to have an electrophoretic feature; a Raman scattering device which has a sample-contact surface, is arranged so that the sample is in contact with the sample-contact surface, and outputs Raman-scattered light when the sample-contact surface is illuminated with measurement light; an optical system which illuminates with the measurement light the sample in contact with the sample-contact surface; a voltage application unit which is provided with the sample cell and applies an electric voltage to the sample so as to bring the one or more materials close to the sample-contact surface by electrophoresis; and a detection unit which detects the Raman-scattered light.

A Raman spectrum detecting method includes a liquid sample contacting step of placing a liquid sample containing a reference substance and a specimen in contact with a detection surface, the reference substance generating a known Raman spectrum having at least one peak therein that is different from peaks in a Raman spectrum generated by the specimen; a scattered light detecting step of irradiating the detection surface in contact with the liquid sample with an excitation light and detecting Raman scattered light occurring from the liquid sample; and a normalizing step of extracting a Raman spectrum signal of the reference substance and a Raman spectrum signal of the specimen from the signal detected in the scattered light detecting step and normalizing a signal intensity of the Raman spectrum signal of the specimen according to an intensity of the Raman spectrum signal of the reference substance.

A new type of dynamiccovalent nanoparticle (NP) building block is reported, exhibiting rapid constitutional adaptation in a NP-bound monolayer of boronate esters, and formation of covalently linked NP assemblies, which despite being connected by covalentbonds, can be fully disassembled on application of a chemical stimulus.
