This article reviews recent advances in terahertz science and technology that rely on confining the energy of incident terahertz radiation to small, very sub-wavelength sized regions. We focus on two broad areas of application for such field confinement: metamaterial-based nonlinear terahertz devices and terahertz near-field microscopy and spectroscopy techniques. In particular, we focus on field confinement in: terahertz nonlinear absorbers, metamaterial enhanced nonlinear terahertz spectroscopy, and in sub-wavelength terahertz imaging systems.

Introduction:Artificial Extracellular Matrices (ECMs) are promising tools for the study of cell behaviors.Methods:Here, we report a protocol for the use of a reconfigurable biocompatible azopolymer thin film through a photoinduced reconfigurable structuration of its surface to study nerve growth, differentiation and cell guidance.Results & Discussion:We show that this protocol combined with a spontaneous self-photoinduced polymer is suitable for time-lapse fluorescence video microscopy and can be easily adapted to electron microscopy techniques (SEM) and near-field imaging techniques (AFM).
