The scanning electron microscopy images of a patterned resist structure (left) before the resist removal and an assembly of fabricated particles (right) with diameter of .
The magnetization hysteresis loop measured for a dry powder sample of disks ( in diameter and in thickness) fabricated using conventional optical lithography technique.
The laser beam intensity passing though an aqueous disk suspension ( disks per ) modulated by an external magnetic field. The field strength is ; pulse duration is .
Optical (a) and fluorescent (b) microscope images of diluted samples taken at the wavelength of emission maxima of fluorescein .
Scheme of functionalization of the disks with IgG. First, thiolate group(s) were introduced into the antibody through a reaction of side epsilon-amino groups with SATA. Then the acetyl group of SATA linker was cleaved with hydroxylamine, and the SH-IgG spontaneously reacted with the gold surface of the disks.
FTIR spectra of as-microfabricated and FITC-IgG functionalized magnetic disks.
