Special Issue Information

Dear Colleagues,

Fluorescent material is an extensively studied issue in the bio-field because it is easy to functionalize and tune fluorescence color. In previous decades, major progress in the synthesis, characterization, and application of fluorescent materials has been accomplished, along with the recent development of nano-, biobased, sensor, imaging and high performance material-based technologies. These advanced technologies promote the application of fluorescent materials in a wide range of applications, for instance, bio-sensing, bio-labelling, bio-tracing, bio-imaging, diseases diagnosis and therapy, etc. To advance the use of fluorescent materials in the bio-field, the development of biocompatible fluorescent materials (BFM) has become increasingly relevant. The intention of this research topic is to describe the biocompatible fluorescent materials (BFM), the recent breakthroughs in this field, and their application in the bio-field. Our attention will be focused on: (i) the preparation of biocompatible fluorescent materials (BFM), including material synthesis and purification and photo physical chemical properties; (ii) the fabrication of novel fluorescent detection devices for bio-objects; and (iii) applications in bio-field, bio-sensing, bio-tracing, bio-imaging and diseases diagnosis and therapy, etc. We hope that this research topic will attract the attention of academic and industrial researchers who are interested in the development of biocompatible fluorescent materials (BFM) and their biological applications. Our goal is to stimulate ideas, methods, and technologies related to chemistry, biology, materials science, medicine, bioscience and electronics in this exciting area.

We welcome manuscripts from diverse aspects of fluorescent materials, including but not limited to:

  • Synthesis and design of novel fluorescent materials with excellent biocompatibility;
  • Preparation of fluorescent materials, including materials synthesis and purification;
  • Multi-scale techniques and morphological studies on biocompatible fluorescent materials;
  • Investigation of fluorescent materials structure-property relationships;
  • Applications in cell-labelling, tumor labelling and therapy, bio-sensing, bio-imaging, etc.;
  • the fabrication of novel fluorescent detection devices for bio-object.

New styryl dyes consisting of N-methylpyridine or N-methylquinoline scaffolds were synthesized, and their binding affinities for DNA in cell-free solution were studied. The replacement of heterocyclic residue from the pyridine to quinoline group as well as variation in the phenyl part strongly influenced their binding modes, binding affinities, and spectroscopic responses. Biological experiments showed the low toxicity of the obtained dyes and their applicability as selective dyes for mitochondria in living cells. Full article

Alzheimer’s disease (AD) is a neurodegenerative disease. Due to its complex pathological mechanism, its etiology is not yet clear. As one of the main pathological markers of AD, amyloid-β (Aβ) plays an important role in the development of AD. The deposition of Aβ is not only related to the degeneration of neurons, but also can activate a series of pathological events, including the activation of astrocytes and microglia, the breakdown of the blood–brain barrier, and the change in microcirculation, which is the main cause of brain lesions and death in AD patients. Therefore, the development of efficient and reliable Aβ-specific probes is crucial for the early diagnosis and treatment of AD. This paper focuses on reviewing the application of small-molecule fluorescent probes in Aβ imaging in vivo in recent years. These probes efficiently map the presence of Aβ in vivo, providing a pathway for the early diagnosis of AD and providing enlightenment for the design of Aβ-specific probes in the future. Full article

Leucine aminopeptidase (LAP) is an important protease that can specifically hydrolyze Leucine residues. LAP occurs in microorganisms, plants, animals, and humans and is involved in a variety of physiological processes in the human body. In the physiological system, abnormal levels of LAP are associated with a variety of diseases and pathological processes, such as cancer and drug-induced liver injury; thus, LAP was chosen as the early biochemical marker for many physiological processes, including cancer. Considering the importance of LAP in physiological and pathological processes, it is critical that high-efficiency and dependable technology be developed to monitor LAP levels. Herein, we summarize the organic small molecule fluorescence/chemiluminescence probes used for LAP detection in recent years, which can image LAP in cancer, drug-induced liver injury (DILI), and bacteria. It can also reveal the role of LAP in tumors and differentiate the serum of cirrhotic, drug-induced liver injury and normal models. Full article
