Multilayer Microcapsules for FRET Analysis and Two-Photon-Activated Photodynamic Therapy.
Microcapsules obtained by layer-by-layer assembly provide a good platform for biological analysis owing to their component diversity, multiple binding sites, and controllable wall thickness. Herein, different assembly species were obtained from two-photon dyes and traditional photosensitizers, and further assembled into microcapsules. Fluorescence resonance energy transfer (FRET) was shown to o...
متن کاملPhotodynamic Therapy and the Development of Metal-Based Photosensitisers
Photodynamic therapy (PDT) is a treatment modality that has been used in the successful treatment of a number of diseases and disorders, including age-related macular degeneration (AMD), psoriasis, and certain cancers. PDT uses a combination of a selectively localised light-sensitive drug (known as a photosensitiser) and light of an appropriate wavelength. The light-activated form of the drug r...
متن کاملA simple mitochondrial targeting AIEgen for image-guided two-photon excited photodynamic therapy
Two-photon excited photodynamic therapy (TP-PDT) is not only able to offer deeper penetration depth but also much more precise 3D treatment than traditional one-photon excited PDT. However, the achievement of TP-PDT requires photosensitizers with large two-photon absorption cross sections, efficient generation of reactive oxygen species, and bright two-photon fluorescence. In this work, we pres...
متن کاملPhotosensitisers - the progression from photodynamic therapy to anti-infective surfaces.
INTRODUCTION The application of light as a stimulus in pharmaceutical systems and the associated ability to provide precise spatiotemporal control over location, wavelength and intensity, allowing ease of external control independent of environmental conditionals, has led to its increased use. Of particular note is the use of light with photosensitisers. AREAS COVERED Photosensitisers are wid...
متن کاملSynthesis of hydrophilic conjugated porphyrin dimers for one-photon and two-photon photodynamic therapy at NIR wavelengths.
We report the synthesis of a series of hydrophilic butadiyne-linked conjugated zinc porphyrin dimers, designed as photodynamic therapy (PDT) agents. These porphyrin dimers exhibit exceptionally high two-photon absorption cross sections (delta(max) approximately 8,000-17,000 GM) and red-shifted linear absorption spectra (lambda(max) approximately 700-800 nm) making them ideal candidates for one-...
