Bacterial infections with emerging resistance to antibiotics require urgent development of antibacterial agents with new core skeletons. Recently, a series of antibacterial agents have been reported based on positively charged organic groups, such as ammonium, guanidine, and phosphonium groups, which can selectively bind and destroy negatively charged bacterial membranes. To achieve imaging-guided precise antibacterial therapy, these positively charged organic groups usually require further decoration with imaging modalities, such as fluorescence. However, most fluorophores with electron-closed shell structures usually suffer from tedious synthetic procedures for preparation. We herein prepare a series of positively charged and deep-red fluorescent supramolecular pyrrole radical cations (P˙+–CB[7]) based on the simple mixing of pyrroles and CB[7] in water under air. The readily available deep-red fluorescent P˙+–CB[7] can not only be used for selective imaging and killing of live Gram-positive bacteria with excellent biocompatibility, but also for imaging of dead Gram-negative bacteria killed by drugs and in vivo monitoring of phagocytosis of bacteria by innate immune cells in zebrafish. It is believed that the deep-red fluorescent pyrrole radical cations as a new core skeleton are promising in bacterial theranostics.

Biomaterials Science

Biomaterials Science is an international high impact journal exploring the science of biomaterials and their translation towards clinical use. Its scope encompasses new concepts in biomaterials design, studies into the interaction of biomaterials with the body, and the use of materials to answer fundamental biological questions. Papers do not necessarily need to report a new biomaterial but should provide novel insight into the biological applications of the biomaterial. Articles that primarily focus on demonstrating novel materials chemistry and bring a molecular picture to bear on a given material’s suitability as a biomaterial are more suited to our companion journal, Journal of Materials Chemistry B. Biomaterials Science publishes primary research and review-type articles in the following areas: molecular design of biomaterials, including translation of emerging chemistries to biomaterials science of cells and materials at the nanoscale and microscale materials as model systems for stem cell and human biology materials for tissue engineering and regenerative medicine (Nano)materials and (nano)systems for therapeutic delivery interactions at the biointerface biologically inspired and biomimetic materials, including bio-inspired self-assembly systems and cell-inspired synthetic tools next-generation biomaterials tools and methods
