Published: February 2018

Purpose Of Review: With this review, we aim to summarize the role of positron emission tomography (PET) and near-infrared fluorescence imaging (NIRF) in the detection of atherosclerosis.

Recent Findings: F-FDG is an established measure of increased macrophage activity. However, due to its low specificity, new radiotracers have emerged for more specific detection of vascular inflammation and other high-risk plaque features such as microcalcification and neovascularization. Novel NIRF probes are engineered to sense endothelial damage as an early sign of plaque erosion as well as oxidized low-density lipoprotein (oxLDL) as a prime target for atherosclerosis. Integrated NIRF/OCT (optical coherence tomography) catheters enable to detect stent-associated microthrombi. Novel radiotracers can improve specificity of PET for imaging atherosclerosis. Advanced NIRF probes show promise for future application in human. Intravascular NIRF might play a prominent role in the detection of stent-induced vascular injury.

Creatinine is an essential biomarker for the clinical diagnosis and treatment of renal insufficiency. Although fluorescent methods are powerful tools for creatinine detection, almost all reported fluorescent probes rely on short-wavelength excitation and a single fluorescent signal, making them susceptible to environmental and operational conditions. In this study, a near-infrared excited, highly sensitive, and multi-output signal sensing system was established using upconversion nanoparticles and 3,5-dinitrobenzoic acid (DNBA) for synergistic luminescent and colorimetric assay for strong visual detection of creatinine.

With the advancement of photodynamic therapy, various photosensitizers have been developed to enhance the efficacy of cancer treatment while minimizing side effects. Recently, near-infrared organic fluorophores have gained significant attention as promising photodynamic agents for cancer therapy due to their tunable photophysical properties, structural versatility, good biocompatibility, high biosafety, and synthetic flexibility. In particular, near-infrared organic photosensitizers offer several notable advantages, including deep tissue penetration, a low fluorescence background for bioimaging, and reduced damage to biological tissues compared to traditional visible-spectrum photosensitizers.

Gold nanoclusters (Au NCs) protected by molecular ligands represent a new class of second-generation near-infrared (NIR-II) luminescent materials that have been widely studied. However, the photoluminescence efficiencies of most NIR-II emitting Au NCs in aqueous solution are generally lower than 0.2%, and to fully exploit the advantages of AuNCs in the NIR-II region, improving their photoluminescence efficiency has become an urgent need.

Prostate-Specific Membrane Antigen (PSMA) is a highly expressed and structurally unique target specific to prostate cancer (PCa). Diagnostic and therapeutic approaches in nuclear medicine, coupling PSMA ligands with radionuclides, have shown significant clinical success. PSMA-PET/CT effectively identifies tumors and metastatic lymph nodes for imaging purposes, while -PSMA-617 (Pluvicto) has received FDA approval for treating metastatic castration-resistant PCa (mCRPC).

Estrogen receptor β (ERβ) is aberrantly expressed in castration-resistant prostate cancer (CRPC). Therefore, a diagnostic and therapeutic ERβ probe not only helps to reveal the complex role of ERβ in prostate cancer (PCa), but also promotes ERβ-targeted PCa therapy. Herein, we reported a novel ERβ-targeted near-infrared fluorescent probe D3 with both imaging and therapeutic functions, which had the advantages of high ERβ selectivity, good optical performance, and strong anti-interference ability.
