“…Із наноцелюлози виготовляють плівки, прозорість яких може досягати 70 %, модуль Юнгадо 11,45 ГПа, а міцність на розрив сягає 42,3 МПа [69,70]. Зазвичай плівки наноцелюлози пропонують використовувати як підкладку для виготовлення гнучкої електроніки [12,63,69], однак їх можна застосовувати як чутливий шар [62,[70][71][72]. Для покращення чи надання нових характеристик плівкам наноцелюлози її можна покривати полімерними матеріалами [12,63,64] чи використовувати для створення композитних матеріалів із полімерами, наночастинками металів, вуглецевими нанотрубками тощо [4,72].…”

Background. Currently, there is a significant number of technologies and materials in the world that are used to manufacture flexible electronics devices. Therefore, a review of various technologies and materials for the manufacture of flexible sensors, which would not be inferior in terms of sensitivity to their solid-state counterparts, is in demand. In addition, most modern flexible electronics technologies are based on the use of artificial polymers, the production of which pollutes the environment and which need to be disposed of at the end of its service life. Therefore, there is an urgent need to find an alternative to artificial polymers, environmentally friendly material. Objective. The purpose of the paper is to determine design and technological features of manufacturing and application of flexible and biodegradable electronic sensors. Methods. The article analyses, classifies and compares different technologies and materials for the manufacture of flexible sensors, which would not be inferior to their solid-state counterparts in terms of sensitivity. The technological features of synthesis and the main characteristics of flexible sensors made on the basis of artificial and biodegradable materials were also compared in the paper. Results. The design and technological features of manufacturing as well as application of flexible electronic sensors in comparison with their solid-state analogues were determined in the paper. Three groups of substrate materials that can be used for the synthesis of flexible sensors have been identified and their performance characteristics analysed. A comparison of different production techniques for flexible electronic sensors in terms of environmental friendliness, cost and manufacturability is carried out. Conclusions. The most promising biodegradable material, on the surface of which one can create a flexible sensor, is nanocellulose. Different types of printing are the most promising production technique for the manufacture of such devices, because they are cheap and can provide high productivity. Based on the obtained results, it is possible to improve the existing and develop new methods of creating flexible electronics devices that do not require recycling.

“…[26][27][28] Besides, Yao et al developed another nanocellulose based quartz crystal microbalance (QCM) humidity sensor with asymmetric structure, presenting the characteristics of short response/recovery time (60 s/15 s), low humidity hysteresis (7.3% RH), and excellent long-term stability. 29 Combining polypyrrole and nanocellulose is to obtain humidity sensor with good humidity sensitivity, remarkable linearity and superior reversibility. 30 A large number of studies had proved that specic surface area and number of hydrophilic groups of the sensing material have a great impact on its sensitivity, response speed, humidity hysteresis performance and long-term stability.…”

“…The transducer is the critical element for determining the sensitivity, sensing range, and detection limit of the biosensors. In the past, several transducers for label-free immunosensing were developed, including quartz crystal microbalances (QCMs) [ 1 , 2 , 3 ], amperometric transducers [ 4 , 5 , 6 , 7 ], cantilever beams [ 8 , 9 , 10 ], electrochemical impedance spectroscopy (EIS) biosensors [ 11 , 12 , 13 , 14 ], preconcentrated immunosensing [ 15 , 16 , 17 ], surface plasmon resonance (SPR) [ 18 , 19 , 20 ], and nanobead Brownian motion [ 21 , 22 , 23 ]. Transducer fabrication of most current technologies is expensive, and they are not easy to mass-produce for rapid screening.…”

In this study, a multiplex detection system was proposed by integrating a localized surface plasmon resonance (LSPR) sensing array and parallel microfluidic channels. The LSPR sensing array was fabricated by nanoimprinting and gold sputter on a polycarbonate (PC) substrate. The polydimethylsiloxane (PDMS) microfluidic channels and PC LSPR sensing array were bound together through (3-aminopropyl)triethoxysilane (APTES) surface treatment and oxygen plasma treatment. The resonant spectrum of the LSPR sensing device was obtained by broadband white-light illumination and polarized wavelength measurements with a spectrometer. The sensitivity of the LSPR sensing device was measured using various ratios of glycerol to water solutions with different refractive indices. Multiplex detection was demonstrated using human immunoglobulin G (IgG), IgA, and IgM. The anti-IgG, anti-IgA, and anti-IgM were separately modified in each sensing region. Various concentrations of human IgG, IgA, and IgM were prepared to prove the concept that the parallel sensing device can be used to detect different targets.
