Figure. Monitoring particle penetration and movement throughout 3D spheroids. Ovarian granulosa cell line
(KGN), cultured as 2D cell monolayers, was labeled with the fluorescent dye, CellTracker Red CMPTX. Cells
were trypsinized, counted, and mixed with varying amounts of fluorescent PC-red microparticles, and seeded
into agarose hydrogels to form spheroids. After 24-hour, confocal images were obtained and reconstructed.
Representative images for 1 bead (A), 100 beads (B), and 10,000 beads (C) per spheroid are shown.

The above is a synthetic strategy towards generation of a DNA-
based hybridization probe capable of signal off-on behavior
with magnetic resonance. Similar to fluorescent molecular bea-
con probes, which yield a fluorescent "on" signal when the
DNA probe hybridizes to an mRNA target of interest, these
magnetic resonance probes are being designed to exhibit an
NMR signal only when in the presence of a target molecule and
remain "off" otherwise. The probe functions through the para-
magnetic relaxation enhancement effect, by which the gadolin-
ium relaxes the fluorine resonance in a magnetic field when in
close proximity.
