(a) CL-based
imaging setup designed for detecting and imaging single
microbeads. (b) Representative CL kinetic curves (left panels) and
averaged CL images (right panels) from the old and new batches of
microbeads during reaction with H2O2, respectively.

(c) Schematic showing the single particle imaging with ECL microscopy
setup. E symbolizes the luminophore (Ru(bpy)32+), while C represents the coreactant (TPrA). (d) SRRF analysis (basic
principle) of multiple frames (images). (e, f) Wide-field ECL images
(left panels), super-resolution ECL images (middle panels), and corresponding
line profiles (drawn from the areas/regions between yellow-colored
arrowhead) of an individual Au nanosphere and separated Au nanospheres,
respectively). Scale bar: 500 nm. Reprinted from ref (80) from American Chemical

in an individual crystalline molecular wire of Ir(piq)3 on an electrode surface (patterned ITO). (h) Representative PL (top),
ECL (middle) images, and corresponding grayscale variations of two
molecular wires along the longitudinal axis. Reprinted from ref (83) with permission from Wiley-VCH,
