“…24 Combining the sensory potential of NDs with an effective structuring of ND composites could be of particular interest for sensory applications. 25,26 For example, surfacestructured ND composites could be tested for scanning NV magnetometry where tip-like diamond structures are applied. 27 NDs are considered to be biocompatible, which is an important parameter regarding the release of the particles to the environment during the fabrication, the machining (the ablation), and the application due to material abrasion.…”

During the past decade, nanodiamonds were demonstrated to be an environmentally friendly, easy-to-handle, accessible additive for polymer science, which also offers sensory-relevant properties. Therefore, nanodiamond-based composites are promising substrates for medical applications, heat transfer materials in electronic devices, or three-dimensional (3D) materials for sensor applications within various fields related to automotive, sensory, and printing applications. One key factor for the implementation of composite materials in modern devices is the precise and energy-efficient structuring of the material. Herein, laser ablation-induced structuring using pulsed laser systems is one of the most applied approaches to achieve micro-and nanostructure surfaces. In this work, nanodiamond additives were demonstrated to have a significant beneficial impact on the laser ablation performance of nanodiamond acrylate composites, in particular, on the laser ablation threshold and the incubation effect. Furthermore, we show that surface modification using the surface graphite content is a crucial parameter for the ablation. Employing a controlled surface graphitization of the nanodiamonds, their optical properties and interaction with the polymer can be influenced to improve the laser ablation performance of composites. In comparison to pure sp 2 carbon additives like graphene oxide, graphitized nanodiamond composites exhibit higher optical density and diffuse light scattering properties. These properties lead to a more surface-located light-induced energy input. The investigations of the laser ablation spot also allowed first insight into the mechanism of the ablation, where the surface graphite of the nanodiamond also influences the bonding strength of the nanodiamond (ND) to the acrylate system. This supports thermal and mechanical ablation and, thus, a decrease of the laser ablation threshold energy. Our results demonstrate that nanodiamond composites are promising materials for laser structuring processing. Further improvement of the diamond surface might even improve their applicability.

“…Two major classes of ORMOSIL depending on the kind of molecular bonds/interactions have been described: class I hybrids and class II hybrids [ 14 , 15 ]. Class I ORMOSILs are hybrid composites that do not contain covalent bonds between organic and inorganic phases, and they could be obtained via the inclusion of organic components, such as various polymers, into the system, leading to the formation of spatial network interactions between the inorganic and organic components of hybrid materials [ 14 , 16 , 17 , 18 ]. Mutual permeation of the 3D networks is achieved by simultaneous gelation of organic and inorganic components.…”

Biocompatible Silica-Polyethylene Glycol-Based Composites for Immobilization of Microbial Cells by Sol-Gel Synthesis

Biocatalysts based on the methylotrophic yeast Ogataea polymorpha VKM Y-2559 immobilized in polymer-based nanocomposites for the treatment of methanol-containing wastewater were developed. The organosilica composites with different matrix-to-filler ratios derived from TEOS/MTES in the presence of PEG (SPEG-composite) and from silicon-polyethylene glycol (STPEG-composite) differ in the structure of the silicate phase and its distribution in the composite matrix. Methods of fluorescent and scanning microscopy first confirmed the formation of an organosilica shell around living yeast cells during sol-gel bio-STPEG-composite synthesis. Biosensors based on the yeast cells immobilized in STPEG- and SPEG-composites are characterized by effective operation: the coefficient of sensitivity is 0.85 ± 0.07 mgO2 × min−1 × mmol−1 and 0.87 ± 0.05 mgO2 × min−1 × mmol−1, and the long-term stability is 10 and 15 days, respectively. The encapsulated microbial cells are protected from UV radiation and the toxic action of heavy metal ions. Biofilters based on the developed biocatalysts are characterized by high effectiveness in the utilization of methanol-rich wastewater—their oxidative power reached 900 gO2/(m3 × cycle), and their purification degree was up to 60%.

“…Fluorescent polymers obtained either by incorporation of fluorophores in the polymer chain or by aggregation (so-called aggregation-induced emission polymers) have attracted a considerable amount of attention, owing to their viscoelastic and mechanical properties that render them useful for device fabrication [ 3 , 4 ]. Alternatively, fluorescent polymer composites may be realized upon incorporation of fluorescent dyes or nanoparticles into nominally transparent polymer matrices, either by adsorption, covalent binding or encapsulation [ 5 ]. These fluorescent composites have been widely used to obtain thin films and microspheres for sensing applications [ 3 , 4 , 5 , 6 ].…”

Luminescent Polymer Composites for Optical Fiber Sensors

Optical fiber sensors incorporating luminescent materials are useful for detecting physical parameters and biochemical species. Fluorescent materials integrated on the tips of optical fibers, for example, provide a means to perform fluorescence thermometry while monitoring the intensity or the spectral variations of the fluorescence signal. Similarly, certain molecules can be tracked by monitoring their characteristic emission in the UV wavelength range. A key element for these sensing approaches is the luminescent composite, which may be obtained upon allocating luminescent nanomaterials in glass or polymer hosts. In this work, we explore the fluorescence features of two composites incorporating lanthanide-doped fluorescent powders using polydimethylsiloxane (PDMS) as a host. The composites are obtained by a simple mixing procedure and can be subsequently deposited onto the end faces of optical fibers via dip coating or molding. Whereas one of the composites has shown to be useful for the fabrication of fiber optic temperature sensors, the other shows promising result for detection of UV radiation. The performance of both composites is first evaluated for the fabrication of membranes by examining features such as fluorescent stability. We further explore the influence of parameters such as particle concentration and density on the fluorescence features of the polymer blends. Finally, we demonstrate the incorporation of these PDMS fluorescent composites onto optical fibers and evaluate their sensing capabilities.
