Abstract: A method for detecting an analyte includes first to third steps. The first step is distributing a sample containing a bead modified with a host molecule that is specifically bound to the analyte in a microchannel using a syringe pump. The second step is irradiating the sample with non-resonant light that is light outside a wavelength range of electronic resonance of the bead. The third step is detecting the analyte based on a signal from a camera that receives the light from the sample.

Abstract: Provided is a novel material used to introduce an exogenous substance into cells. Also provided is a method for introducing an exogenous substance into target cells using this material. The present invention provides an exosome that is used to introduce an exogenous substance into target cells, wherein the exosome contains one type or two or more types of an exogenous substance and a substance that induces macropinocytosis in the target cells. The present invention also provides a composition containing the exosome and a method for introducing an exogenous substance into cells using this exosome.

Abstract: The pharmaceutical composition for inhibiting expression of CD47 in tumor cells provided by the present invention contains: exosomes produced by cultured tumor cells in an amount effective for inhibiting expression of the CD47; and a pharmaceutically acceptable carrier.

Abstract: The method of producing induced lightweight exosomes (iLE) provided by the present invention includes preparing a cell culture containing prescribed cultured cells; supplying at least once an artificially produced synthetic peptide to the cell culture and culturing the cell culture for a prescribed interval; and obtaining exosomes produced by the cultured cells following culturing. Here, the synthetic peptide is provided with: (1) an exosome-inducing peptide sequence and (2) a CPP sequence, and has a total number of amino acid residues of 100 or less.

Abstract: An assembling apparatus assembles beads different in particle size from each other. The assembling apparatus includes a substrate and a photothermal light source. The substrate is constructed to be able to hold a sample in which the beads are dispersed. The photothermal light source irradiates the substrate or the sample with laser beams to thereby produce a temperature difference in the sample.

Abstract: A polymer membrane for cancer cell detection having a surface provided with a mold having a three-dimensional structure complementary to a portion of a steric structure of a cancer cell to be detected; a method of producing the same; and a cancer cell detection device including the polymer membrane are provided. The polymer membrane for cancer cell detection can be obtained, for example, by a producing method including: polymerizing monomers in presence of cancer cells to be detected, to form a cancer cell-containing polymer membrane having the cancer cells incorporated therein; and removing at least part of the cancer cells incorporated in the cancer cell-containing polymer membrane.
