Fig. 2: Top-down light-induced acceleration of antigen–antibody reactions with a membrane protein.

a Schematic diagram of the process of forming a three-dimensional structure by an antigen–antibody reaction with a defocused laser spot diameter. b Optical transmission image of the assembled structure of CD80 as the target and probe beads modified with anti-CD80 antibody. The pressure-driven flow is in +y-direction, which appears to be inverted in the microscope transmission image. Protein concentration dependence of c, total assembly area of the complex of CD80 and probe beads, and d ratio of the black area (multi-layered part). In c and d, error bars indicate standard deviation. Individual data points are shown as small plots.
