“…The swelling ratio of hydrogels containing cavitated microchannels was higher than for hydrogels without microchannels but did not interfere with infusion of fluid into the hydrogel through the microchannels. The swelling behavior observed in the presence of microchannels may be appealing for applications requiring a large volume change or a fast response time, e.g., biosensing [ 39 ] and controlled release. [ 40 ]…”

With the development of biotechnology and the miniaturization of sensors, wearable devices have attracted extensive attention for real-time and non-invasive health monitoring at the molecular level. Among these, sensors for electrolytes analysis play an essential role in monitoring body physiological functions and metabolic activities. Herein, this review firstly summarizes the recent advances in electrolytes sensing via wearable devices, focusing on the most commonly adopted ion-selective electrodes, optical sensors and sensing platforms for effective body fluid collection and analysis. Innovative strategies based on nanomaterials engineering to achieve biosensing reliability, mechanical robustness as well as biocompatibility are also presented. Moreover, novel printable fabrication approaches to realize integrated wearable sensing systems with desirable compatibility and versatility are introduced. Finally, the challenges for practical applications and the perspectives on accurate and multi-functional sensing based on integrated wearable devices are discussed.

“…Biosensors are special forms of sensors based on inorganic biological materials or the organism itself (such as organs, bodies, etc.). Bioactive substances are sensitive substances that can selectively identify specific test substances by classifying biochemical reactions, and convert biochemical reactions into metabolic signals, living species and small chemical substances [6][7]. Biosensors have been used in industrial control, food and drug analysis, environmental monitoring and technology due to their advantages of high sensitivity, fast speed, high accuracy, and simplicity.…”

The use of functional polymer materials to obtain high-performance biosensors is currently a research hotspot in the field of analysis and materials. Polymer materials have the advantages of good biocompatibility, easy design and controllable preparation of reactive groups, and rich functional types, which are helpful to construct biosensor interfaces with excellent performance. This work aims to study the application of functional polymer materials in environmental biosensors in the context of the Internet of Things, prepare silver nanocubes on Nafion membranes with ATP as a buffer, and establish a new optical detection method. Formaldehyde based color change of the film. In addition, a new method for detecting temperature and spermine using the conformational changes of polythiophene (PT) derivatives under certain conditions was established. According to the color and fluorescence changes of PT induced by iodide ions in the range of 25.5℃-50.5℃, a rapid and sensitive method for temperature detection was established. The establishment of this method shows that polythiophene derivatives can be used as a new type of temperature sensor, thus expanding the application range of PT. In addition, to further validate the method, real beef and chrysanthemum samples were tested, and the detection recoveries ranged from 85.6% to 103%, indicating that the method is feasible for spermine detection.
