Large-scale structural color flexible coatings have been hard to create, and patterning color on them is key to many applications, including large-area strain sensors, wall-size displays, security devices, and smart fabrics. To achieve controlled tuning, a micro-imprinting technique is applied here to pattern both the surface morphology and the structural color of the polymer opal films (POFs)....

Traditionally, molecular imprinting of proteins has proved challenging due to solvent limitations, recovery of the protein template, and most importantly, lack of specificity due to the large number of possible interaction sites. In this work, a surface imprinting technique has been developed to template hydrogel materials for specific protein recognition. Our model protein, the immunoglobulin ...

Purpose: This article provides an overview of the monitoring technique for nanoimprint. Optical and electrical monitoring approaches that have the potential for detecting and monitoring mold deformation and cavity filling in nanoimprint will be reviewed. The major part is devoted to the review of an in-situ mold filling monitoring system based on capacitance measurement for nanoimprinting opera...

Molecular imprinting is earning worldwide attention from researchers in the field of sensing and diagnostic applications, due to its properties of inevitable specific affinity for the template molecule. The fabrication of complementary template imprints allows this technique to achieve high selectivity for the analyte to be sensed. Sensors incorporating this technique along with surface plasmon...

Molecular imprinting is the technology of creating artificial recognition sites in polymeric matrices which are complementary to the template in their size, shape and spatial arrangement of the functional groups. Molecularly imprinted polymers (MIPs) and their incorporation with various transducer platforms are among the most promising approaches for detection of several analytes. There are a v...

Imaging mass spectrometry (IMS) is a powerful technique that enables analysis of various molecular species at high spatial resolution with low detection limits. In contrast to the matrix-assisted laser desorption/ionization (MALDI-MS) approach, surface-assisted (SALDI) can be more effective in small molecules due absence interfering background signals m/z ranges. We developed functionalized TiO...

The creation of label-free biosensors capable of accurately detecting trace contaminants, particularly small organic molecules, is of significant interest for applications in environmental monitoring. This is achieved by pairing a high-sensitivity signal transducer with a biorecognition element that imparts selectivity towards the compound of interest. However, many environmental pollutants do ...

The ambient mass spectrometry technique, desorption electrospray ionization mass spectrometry (DESI-MS), is applied for the rapid identification and spatially resolved relative quantification of chlorophyll degradation products in complex senescent plant tissue matrixes. Polyfunctionalized nonfluorescent chlorophyll catabolites (NCCs), the "final" products of the chlorophyll degradation pathway...
