PET and NIR fluorescence imaging are sensitive imaging modalities that are becoming increasingly important in clinical practice (27, 30, 39 ⇓ –41). We show here that particularly 64 Cu-NOTA-AC133 mAb-mediated microPET yields high-quality, high-resolution images with outstanding tumor-to-background contrast.

GLUT1 is the main transporter for 2-deoxy-2-[18F]fluoro-D-glucose (2-[18F]FDG), the golden standard of positron emission tomography (PET) imaging in oncology. The present study's goal was to develop novel glucose-based dual imaging probes for their use in tandem PET and fluorescence (Fl) imaging. A dual-modality probe for positron-emission tomography (PET) and fluorescence imaging was synthesized using the developed BaAn (Boc)Sar chelator. The c (RGDyK) 2 peptide (denoted as RGD 2) and fluorescence dye Cy5.5 were conjugated with BaAn (Boc)Sar to form BaAnSar-RGD 2 -Cy5.5. Then, BaAnSar-RGD 2 -Cy5.5 was labeled with 64 Cu in ammonium acetate Here, we describe the synthesis of a bimodal imaging probe (PET/fluorescence) for imaging GLP-1R expression in the pancreas and in pancreatic islet cell tumors. The conjugation of a bimodal imaging tag containing a near-infrared fluorescent dye, and the copper chelator sarcophagine to the GLP-1R targeting peptide exendin-4 provided the basis for the bimodal imaging probe. In the PET sensors, photoinduced electron transfer makes the transfer of recognition information to fluorescence signal between receptor and fluorophore come true.

68. Ga-labeling 148 AIM To monitor cells in vivo or to detect the sentinel lymph node, we developed a PET/MRI silica nanoprobe with an enhanced near-infrared fluorescence signal. METHODS We developed enhanced near-infrared fluorescent (NIRF) magnetic silica nanoparticles, MNP-SiO2(NIR797), that encapsulate NIRF dye in the silica. We applied this probe to visualizing cells in the deep tissue of mice using NIRF Fluorescence quenching by photoinduced electron transfer: a reporter for conformational dynamics of macromolecules. Photoinduced electron transfer (PET) between organic fluorophores and suitable electron donating moieties, for example, the amino acid tryptophan or the nucleobase guanine, can quench fluorescence upon van der Waals contact and thus Photoinduced electron transfer (PET) is an excited state electron transfer process by which an excited electron is transferred from donor to acceptor. Due to PET a charge separation is generated, i.e., redox reaction takes place in excited state (this phenomenon is not observed in Dexter electron transfer).

By simple tail vein injection, PiF stains pancreatic β cells specifically and allows intraoperative fluorescent imaging of pancreatic islets. Dual-modality PET/fluorescence imaging could provide non-invasive whole-body disease detection and intraoperative fluorescence guidance, and therefore improve prostate cancer treatment. In this study, the anti-PSCA antibody fragment A11 cys-minibody (A11 cMb) was used to generate a novel dual-modality imaging probe.

Figure \(\PageIndex{2}\) shows the detailed process of how PET works in the fluorescence molecular sensor.

The same result can be obtained by the rule of thumb when we note that the oxidation potential of the receptor is +1.0 V as above and that the oxidation potential of the anthracene ﬂuorophore is +1.0 V. So DG PET is 0.0 eV again. Direct Tumor Imaging: PET Fluorescence Biomarker Imaging. PET fluorescence antibodies— A popular way to mark cancerous tissue is to target cancer cells directly, through the imaging of specific biomarkers expressed on the extra-cellular membrane of cancer cells.
