Abstract
Despite the wide application of the traditional NIR-I phototheranostic platforms in basic research and clinical studies, problems such as tissue scattering, auto-fluorescence combined with aggregation caused quenching hamper precise image-guided phototherapy. Herein, we developed a multifunctional NIR-II phototheranostic platform using a novel AIE-based dye (ZSY-TPE) for single laser-activated imaging-guided combined photothermal and photodynamic therapies of tumors and pathogens. As confirmed through in vivo studies, the ZSY-TPE dots displayed precise and efficient high-performance NIR-II imaging-guided combination phototherapy against 4T1 tumor as well as S. aureus-infected mice models without any noticeable side effects. The current study demonstrates ZSY-TPE as a powerful phototheranostic platform for precise NIR-II fluorescence/PA imaging and synergistic photodynamic/photothermal therapy of tumors and bacterial infections.
期刊介绍：
Biomaterials is an international journal covering the science and clinical application of biomaterials. A biomaterial is now defined as a substance that has been engineered to take a form which, alone or as part of a complex system, is used to direct, by control of interactions with components of living systems, the course of any therapeutic or diagnostic procedure. It is the aim of the journal to provide a peer-reviewed forum for the publication of original papers and authoritative review and opinion papers dealing with the most important issues facing the use of biomaterials in clinical practice. The scope of the journal covers the wide range of physical, biological and chemical sciences that underpin the design of biomaterials and the clinical disciplines in which they are used. These sciences include polymer synthesis and characterization, drug and gene vector design, the biology of the host response, immunology and toxicology and self assembly at the nanoscale. Clinical applications include the therapies of medical technology and regenerative medicine in all clinical disciplines, and diagnostic systems that reply on innovative contrast and sensing agents. The journal is relevant to areas such as cancer diagnosis and therapy, implantable devices, drug delivery systems, gene vectors, bionanotechnology and tissue engineering.
