要旨

Tumor targeted hollow double-layered polymer nanoparticles (HDPNs) with S-nitrosothiols for nitric oxide (NO)-release as chemotherapy were described. Via a two-stage distillation precipitation co-polymerization, simple post-treatment and S-nitrosothiol modification, the S-nitroso HDPNs showed pH and glucose dual responsiveness. This would benefit accurate binding with the sialic acid over-expressed cancer cells, providing prerequisites for the disulfide polymer assisted cell uptake, intracellular GSH induced decomposition and rapid NO release. Confocal microscopy and cytotoxicity assay with normal versus tumor cells demonstrated in vitro recognition, intracellular delivery ability and tumor cell targeting cytotoxicity. Especially worth mentioning, the inevitable small amount of NO leakage in the transmission would take part in normal physiological activities and not cause serious side effects, providing a possible solution to avoid the intolerable side effects of traditional chemotherapy treatments for cancer.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry B are listed below. This list is neither exhaustive nor exclusive. Antifouling coatings Biocompatible materials Bioelectronics Bioimaging Biomimetics Biomineralisation Bionics Biosensors Diagnostics Drug delivery Gene delivery Immunobiology Nanomedicine Regenerative medicine & Tissue engineering Scaffolds Soft robotics Stem cells Therapeutic devices image block All articles published in Journal of Materials Chemistry B from 2019 onwards will be indexed in MEDLINE®. Articles that primarily focus on providing insight into the underlying science and performance of biomaterials within a biological environment are more suited to our companion journal, Biomaterials Science.
