摘要

我们报道了一种氟化胶束纳米系统的发展，其19F-MRI信号可以通过外部刺激选择性地变暗。光活化猝灭单元（二茂铁）在胶体胶束中与超氟化PERFECTA探针共包被。虽然原始胶束是MRI响应（“开”状态），但它们的光照射触发了PERFECTA的“关”MRI状态。

Light-triggered quenching of the ¹⁹F-MRI signal from micelle-encapsulated PERFECTA.

We report the development of a fluorinated micellar nanosystem whose ¹⁹F-MRI signal can be selectively dimmed by application of an external stimulus. A photo-activatable quencher unit (ferrocene) was co-encapsulated with the superfluorinated PERFECTA probe in colloidal micelles. While pristine micelles were MRI responsive ("On" state), their irradiation by light triggered the "Off" MRI-state of PERFECTA.

期刊介绍： Nanoscale Horizons stands out as a premier journal for publishing exceptionally high-quality and innovative nanoscience and nanotechnology. The emphasis lies on original research that introduces a new concept or a novel perspective (a conceptual advance), prioritizing this over reporting technological improvements. Nevertheless, outstanding articles showcasing truly groundbreaking developments, including record-breaking performance, may also find a place in the journal. Published work must be of substantial general interest to our broad and diverse readership across the nanoscience and nanotechnology community.
