— This invention is the formulation of a SPECT nanoparticle probe for the detection of MMP activity. The surface of a 10 nm-sized gold nanoparticle is functionalized through a thiol anchor with a peptide that is cleaved in the presence of MMP9. The surface is also functionalized with methoxy polyethyl…
— Background: Near Infrared (NIR) fluorescence can be highly useful in biological systems as it is highly sensitive and allows for detection and imaging of physiological and molecular processes in cells and living organisms. However, radiometric imaging is difficult in the NIR region of the light spec…
— The sigma-2 (σ2) receptor is an important target for the development of molecular probes in oncology because of its 10-fold higher density in proliferating tumor cells than in quiescent tumor cells, and the observation that σ2 receptor agonists are able to kill tumor cells via apoptotic …
