Highly Sensitive Detection of Human Serum Albumin Biomarker Using a Molecularly Imprinted Polymer‐Based Electrochemical Capacitance Sensor

Advanced Sensor Research, Volume 4, Issue 11, November 2025.
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 ...

Photoresponsive Multilayer Films of Chitosan and an Azopolymer

Journal of Renewable Materials, 2015
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

ACS Applied Polymer Materials, 2020
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,

Polarization‐Driven Molecular Alignment of Azopolymer for Dual‐Encrypted and Moiré Animation‐Based Anti‐Counterfeiting

Advanced Functional Materials, Volume 35, Issue 31, August 1, 2025.
A multi‐layered anti‐counterfeiting platform is developed based on an azopolymer (PAzo) system. By leveraging the molecular orientation control of PAzo under linearly polarized light (LPL), encrypted patterns are fabricated that remain invisible under standard conditions and require polarized optical microscopy (POM) for decryption.
