Abstract: An object identification method capable of quickly and accurately identifying a virus or the like is provided. An object identification method according to an aspect of the present disclosure includes feeding an object dispersed in a solvent to a micro-channel, and applying an AC (Alternating Current) voltage to a measurement electrode provided at the micro-channel and measuring an AC characteristic of the object when the object passes through the micro-channel. Then, a combined impedance and a phase are determined by using the measured AC characteristic, and the object is identified by using the determined combined impedance and the phase.

Abstract: A structure body includes a base material and a siloxane based molecular membrane formed on the base material by use of an organic compound represented by Formula (1) or Formula (2): wherein any one of R1 to R5 is an amino group, others of R1 to R5 are each independently hydrogen or an alkyl group, R7 to R9 are each independently any one of hydroxy group, alkoxy group, alkyl group, and phenyl group on condition that one or more of R7 to R9 are each independently a hydroxy group or an alkoxy group, and R6 is an alkyl group.

Abstract: A conjugate includes a binding substance having an activity to bind to a target substance and a label causing a detectable phenomenon. A molecular weight of the binding substance is less than a molecular weight of an immunoglobulin.

Abstract: A method for detecting a plurality of target substances using a plurality of conjugates each including a binding substance and a label is provided. The binding substance has an activity to bind to one of the target substances and the label causes a detectable phenomenon. The method includes binding at least some of the plurality of conjugates with the plurality of target substances, removing a remainder of the plurality of conjugates that is not bound to the plurality of target substances, and detecting the label. A molecular weight of the binding substance is less than a molecular weight of an immunoglobulin.

Abstract: A complex includes photoresponsive liposomes, a first buffer solution, and a second buffer solution. Each of the photoresponsive liposomes includes a membrane that contains azobenzene compound and phospholipid and a membrane binding site that is immobilized to the membrane and bindable to a target substance. The first buffer solution is filled inside the photoresponsive liposomes. The second buffer solution exists outside of the photoresponsive liposomes. The first buffer solution has a composition that is different from that of the second buffer solution.
