Robust Fluorescent Response of Micropatterned Multilayered Films

Abstract: We demonstrate that photobleaching can be significantly suppressed in fluorescentlabeled polyelectrolyte layer-by-layer (LbL) films by efficient spatial isolation of the dye molecules using multilayered architecture. The films exhibited excellent temporal stability under high excitation power where the bulk films suffered a significant photobleaching. Quenching of the fluorescence caused by the resonant energy transfer between the dye molecules and gold nanoparticles exhibited a weak distance dependence with s… Show more

“…1À6 Various approaches have been suggested for the fabrication of free-standing nanomembranes based on organic polymers and/or inorganic materials: spin-casting of films, layer-by-layer assembly of polyelectrolyte multilayers, 8 cross-linking of self-assembled monolayers, 9 and assembly of triblock copolymers. 10,11 Loading materials such as gold nanoparticles 12 or carbon nanotubes 13 make membranes robust and electrically conductive. However, these methods are often time-consuming and have some limitations in terms of achievable electrical and electrochemical membrane performance as well as scale-up.…”

“…In fact, adding QDs with surface passivation into the polymer template was demonstrated as a more effective way to reduce photoemission quenching than organic dye. 30 Another study reported that the PL intensity of QDs in colloidal solution can be signicantly enhanced by adding proper polymers. 31…”

“…The reaction was performed in PAH solution (12.5 mg mL −1 ) at pH 9.5 (buffered by sodium carbonate) by the addition of 0.4 wt% RhBITC with respect of the concentration of PAH. The product solution was separated by chromatography (Sephadex G25-150) (Richter and Kirstein, 1999;Singamaneni et al, 2007). From the molar extinction coefficient of RhBITC (ε o = 10.7 × 10 4 L mol −1 cm −1 ), the mean molar ratio of dye to PAH monomers was estimated to be in the ratio 1:6150.…”
