We have studied the photopatterning of a gold surface functionalized with a self-assembled monolayer of an o-nitrobenzyl-based photouncaging ligand bound to the gold surface with a dual thiol anchor. We find that the dose of UV light required to indu

We describe a lithographic method for directly patterning the adhesive properties of amine-rich layer-by-layer assembled polymer films, useful for positioning metal and other nanostructures. The adhesive properties of the films are sufficiently robus

Convective (or evaporation-induced) self-assembly is a standard technique for depositing uniform, poly-crystalline coatings of nanospheres across multiple square centimeters on the timescale of minutes. In this paper, we present a variation of this t

We study the creation of fluorescence patterns inside a gelatin gel by way of two-photon photoactivation of 7-azido-4-trifluoromethyl-1,2-benzopyrone (azidocomarin 151) contained in the gel matrix. As ultrafast light pulses are focused into the gel,

We propose the use of amine-rich polyelectrolyte multilayers as a versatile, high quality, tunable adhesive surfaces for biomedical and nanotechnological applications. The films are simple to fabricate under mild conditions and provide at least as go

We present a variation of a standard convective self-assembly technique, where the drying meniscus is restricted by a straight-edge located approximately 100 μm above the substrate adjacent to the drying zone. We find this technique to yield films a

The process of spontaneous emission can be dramatically modified by optical microstructures and nanostructures. We have studied the modification of fluorescence dynamics using a variable thickness polymer spacer layer fabricated using layer-by-layer
