“…Inorganic materials such as graphene are ideal sources for SERS substrate development [87,88]. Studies have shown that graphene fold structures can improve the performance of hybrid SERS substrates [89,90]. For example, Chen et al [40] prepared a high-performance hybrid SERS substrate by depositing Au nanoparticles onto a pleated graphene surface (Figure 4f).…”

“…Laser-scribed graphene (LSG) technology has been used to develop flexible SERS substrate by generating silver dendrites (AgD) directly on a soft substrate, in which the laser allowed the controlled reduction of graphene oxide for the following growing of AgD by electrodeposition. The SERS signal can be enhanced by the combination of the inherent chemical enhancement of graphene and the electromagnetic enhancement of the Ag nanostructures [90]. Figure 7a shows images captured during the fabrication process: (i) a sample of flexible LSG and (ii) GO/LSG, (iii) a zoomed-out view of the LSG surface, and (iv) a zoomed-in view of AgD [90].…”

Surface-enhanced Raman scattering (SERS) is a cutting-edge technique for highly sensitive analysis of chemicals and molecules. Traditional SERS-active nanostructures are constructed on rigid substrates where the nanogaps providing hot-spots of Raman signals are fixed, and sample loading is unsatisfactory due to the unconformable attachment of substrates on irregular sample surfaces. A flexible SERS substrate enables conformable sample loading and, thus, highly sensitive Raman detection but still with limited detection capabilities. Stretchable SERS substrates with flexible sample loading structures and controllable hot-spot size provide a new strategy for improving the sample loading efficiency and SERS detection sensitivity. This review summarizes and discusses recent development and applications of the newly conceptual stretchable SERS substrates. A roadmap of the development of SERS substrates is reviewed, and fabrication techniques of stretchable SERS substrates are summarized, followed by an exhibition of the applications of these stretchable SERS substrates. Finally, challenges and perspectives of the stretchable SERS substrates are presented. This review provides an overview of the development of SERS substrates and sheds light on the design, fabrication, and application of stretchable SERS systems.

Given the advancements in modern living standards and technological development, conventional smart devices have proven inadequate in meeting the demands for a high-quality lifestyle. Therefore, a revolution is necessary to overcome this impasse and facilitate the emergence of flexible electronics. Specifically, there is a growing focus on health detection, necessitating advanced flexible preparation technology for biosensor-based smart wearable devices. Nowadays, numerous flexible products are available on the market, such as electronic devices with flexible connections, bendable LED light arrays, and flexible radio frequency electronic tags for storing information. The manufacturing process of these devices is relatively straightforward, and their integration is uncomplicated. However, their functionality remains limited. Further research is necessary for the development of more intricate applications, such as intelligent wearables and energy storage systems. Taking smart wear as an example, it is worth noting that the current mainstream products on the market primarily consist of bracelet-type health testing equipment. They exhibit limited flexibility and can only be worn on the wrist for measurement purposes, which greatly limits their application diversity. Flexible energy storage and flexible display also face the same problem, so there is still a lot of room for development in the field of flexible electronics manufacturing. In this review, we provide a brief overview of the developmental history of flexible devices, systematically summarizing representative preparation methods and typical applications, identifying challenges, proposing solutions, and offering prospects for future development.

Flexible surface‐enhanced Raman scattering (SERS) substrates have recently attracted growing research interests in real‐world applications due to their unique advantage of sensitivity and flexibility. Reviewing the latest progress of flexible SERS substrates is very important for further development of high‐quality detection platforms. Herein, the recent developments of flexible SERS substrates in fabrications and applications are introduced. First, three categories of current flexible SERS platforms including paper‐based SERS substrates, polymer‐based SERS substrates, and inorganic materials‐based SERS substrates are demonstrated in depth. Then, the focus is moved to the applications of flexible SERS substrates. Combining swab strategies, lateral flow strips, paper‐based microfluidics, and in situ detection techniques, flexible SERS platforms provide intriguing applications in various fields. The challenges are also identified for practical applications on account of substrates’ uniformity, quantitative accuracy, multiplex detection ability, and overall cost. It is believed this review will be of help for researchers to design and fabricate flexible SERS substrates with higher performance and lower cost, and finally realize the practical applications.
