Holographic fabrication of reconfigurable diffractive elements [PDF]
The fabrication of Diffractive Optical Elements (DOEs) involves the analog patterning of material surfaces on the scale of light wavelength. This typically requires multi-step lithographic processes.

An electrosynthesized protein‐imprinted polymer (poly(azo‐BBY)) enables probe‐free, real‐capacitance detection of human serum albumin at 0.02 ng mL−1 within a 0.25–3.0 ng mL−1 window. The device uses a redox‐mediator‐free architecture and maintains selectivity against common interferents, illustrating a simple, scalable route to high‐sensitivity ...

Photoinduced deformation of azopolymer nanometric spheres
Nanometric spheres of an azopolymer are obtained by micellization from a solution. We observe photoinduced deformation of the individual nanospheres under white light illumination. The diameter expands up to 35% parallel to the substrate surface. The magnitude of the force that is necessary to produce the same effect is estimated.

Light-surface coupling in deep azopolymer surface relief diffraction gratings
Surface relief gratings (SRGs) are fundamental diffractive elements for optical wavefront control, but in azobenzene-containing polymers their inscription at large modulation depths is limited by growth saturation and profile distortions, which hinder ...

Optically Active Multilayer Films Based on Chitosan and an Azopolymer
The layer-by-layer technique has been widely adopted for the fabrication of nanostructures with tailored properties. In this work, photoactive multilayer films consisting of alternating layers of chitosan and an azopolymer were developed by this method.

Photoresponsive Multilayer Films of Chitosan and an Azopolymer
The main goal of this work was the development of photoactive multilayer films. Taking into account that chitosan is a biodegradable, biocompatible, nontoxic, and antibacterial biopolymer, the fabrication of chitosanbased multilayer films can be an interesting pathway to obtain biopolymer-based films in which properties can be combined with a light ...

Influence of Photoanisotropies on Light-Controllable Structuration of Azopolymer Surface
The capability to optically control surface structuration of azopolymer films is an important goal in different research fields, enabling remote activation and tuning of associated processes mediated by the surface. In this work, two amorphous azopolymers, structurally engineered in order to exhibit linear and circular photoinduced optical anisotropies,
