“…Several other studies reported for the microcantilever sensor [42], optical fiber-based tweezer [43], fiber microlens [44] etc. [45] have used FIB milling. Additionally, in terms of advanced LOF technology, Principe et al reported a novel integration of phase-gradient plasmonic metasurfaces over the optical fiber tip, named as optical fiber meta-tip, using FIB technology [46].…”

Point-of-care and in-vivo bio-diagnostic tools are the current need for the present critical scenarios in the healthcare industry. The past few decades have seen a surge in research activities related to solving the challenges associated with precise on-site bio-sensing. Cutting-edge fiber optic technology enables the interaction of light with functionalized fiber surfaces at remote locations to develop a novel, miniaturized and cost-effective lab on fiber technology for bio-sensing applications. The recent remarkable developments in the field of nanotechnology provide innumerable functionalization methodologies to develop selective bio-recognition elements for label free biosensors. These exceptional methods may be easily integrated with fiber surfaces to provide highly selective light-matter interaction depending on various transduction mechanisms. In the present review, an overview of optical fiber-based biosensors has been provided with focus on physical principles used, along with the functionalization protocols for the detection of various biological analytes to diagnose the disease. The design and performance of these biosensors in terms of operating range, selectivity, response time and limit of detection have been discussed. In the concluding remarks, the challenges associated with these biosensors and the improvement required to develop handheld devices to enable direct target detection have been highlighted.

“…IB techniques, including ion implantation, irradiation, and focused IB (FIB) processing, have been extensively used to modulate the properties of nanomaterials. [ 154,155 ] Ion implantation and irradiation correspond to the continuous interaction between implanted ions and atoms and electrons in polymers, which leads to degradation, crosslinking, and degradation of small molecules, thereby enabling the processing of devices. [ 156,157 ] FIB is more commonly applied in micro‐ and nanofabrication, either through lithography, milling, or induced processing (e.g., deposition and etching), which involves material removal from the substrate and material addition.…”

Current and Future Trends for Polymer Micro/Nanoprocessing in Industrial Applications

Polymers are widely used in optical devices, electronic devices, energy‐harvesting/storage devices, and sensors, owing to their low weight, excellent flexibility, and simple fabrication process. With advancements in micro/nanoprocessing techniques and more demanding application requirements, it is becoming necessary to realize high‐resolution fabrication of polymers to prepare miniaturized devices. This is particularly because conventional processing technologies suffer from high thermal stress and strong adhesion/friction, which can irreversibly damage the micro/nanostructures of miniaturized devices. In addition, although the use of advanced fabrication methods to prepare high‐resolution micro/nanostructures is explored, these methods are limited to laboratory research or small‐batch production. This review focuses on the micro/nanoprocessing of polymeric materials and devices with high spatial precision and replication accuracy for industrial applications. Specifically, the current state‐of‐the‐art techniques and future trends for micro/nanomolding, high‐energy beam processing, and micro/nanomachining are discussed. Moreover, an overview of the fabrication and applications of various polymer‐based elements and devices such as microlenses, biosensors, and transistors is provided. These techniques are expected to be widely applied for multiscale and multimaterial processing as well as for multifunction integration in next‐generation integrated devices, such as photoelectric, smart, and biodegradable devices.
