One of the major challenges in surgical oncology is the intraoperative discrimination of tumoural versus healthy tissue. Until today, surgeons rely on visual inspection and palpation to define the tumoural margins during surgery and, unfortunately, for various cancer types, the local recurrence rate thus remains unacceptably high. Near-infrared (NIR) fluorescence imaging is an optical imaging technique that can provide real-time preoperative and intraoperative information after administration of a fluorescent probe that emits NIR light once exposed to a NIR light source. This technique is safe, cost-effective and technically easy. Several NIR fluorescent probes are currently studied for their ability to highlight neoplastic cells. In addition, NIR fluorescence imaging holds great promise for sentinel lymph node mapping. The aim of this manuscript is to provide a literature review of the current organic NIR fluorescent probes tested in the light of human oncology and to introduce fluorescence imaging as a valuable asset in veterinary oncology.

Fluorescent Nanodiamonds

Fluorescent nanodiamonds (FNDs) are a new class of carbon nanomaterials that offer great promise for biological applications such as cell labeling, imaging, and sensing due to their exceptional optical properties and biocompatibility. Implementation of these applications requires reliable and precise surface functionalization. Although diamonds are generally considered inert, they typically possess diverse surface groups that permit a range of different functionalization strategies. This review provides an overview of nanodiamond surface functionalization methods including homogeneous surface termination approaches (hydrogenation, halogenation, amination, oxidation, and reduction), in addition to covalent and non-covalent surface modification with different functional moieties. Furthermore, the subsequent coupling of biomolecules onto functionalized nanodiamonds is reviewed. Finally, biomedical applications of nanodiamonds are discussed in the context of functionalization.

The Past

Time-gated (TG) fluorescence imaging (TGFI) has attracted increasing attention within the biological imaging community, especially during the past decade. With rapid development of light sources, image devices, and a variety of approaches for TG implementation, TGFI has demonstrated numerous biological applications ranging from molecules to tissues. The paper presents inclusive TG implementation mainly based on optical choppers and electronic units for synchronization of fluorescence excitation and emission, which also serves as guidelines for researchers to build suited TGFI systems for selected applications. Note that a special focus will be put on TG implementation based on optical choppers for TGFI of long-lived probes (lifetime range from microseconds to milliseconds). Biological applications by TG imaging of recently developed luminescent probes are described.
