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.

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.
