“…Sensors derived from other carbon materials (graphene CNTs, CNFs) require additional steps of pattern transfer or printing onto flexible substrates, post their synthesis, to facilitate a complete microdevice fabrication. [235][236][237] LP-C not only offers a single-step fabrication, it even reduces the number of post-processing steps owing to its already functional large surface area. Its porous surface can indeed be further utilized to support other active nanoparticles to increase the sensitivity of the device toward the analyte, which increases its utility in sensor fabrication manifolds.…”

Fabricating electronic devices from natural, renewable resources is a common goal in engineering and materials science. In this regard, carbon is of special significance due to its biocompatibility combined with electrical conductivity and electrochemical stability. In microelectronics, however, carbon's device application is often inhibited by tedious and expensive preparation processes and a lack of control over processing and material parameters. Laser‐assisted carbonization is emerging as a tool for the precise and selective synthesis of functional carbon‐based materials for flexible device applications. In contrast to conventional carbonization via in‐furnace pyrolysis, laser‐carbonization is induced photo‐thermally and occurs on the time‐scale of milliseconds. By careful selection of the precursors and process parameters, the properties of this so‐called laser‐patterned carbon (LP‐C) such as porosity, surface polarity, functional groups, degree of graphitization, charge‐carrier structure, etc. can be tuned. In this critical review, a common perspective is generated on laser‐carbonization in the context of general carbonization strategies, fundamentals of laser‐induced materials processing, and flexible electronic applications, like electrodes for sensors, electrocatalysts, energy storage, or antennas. An attempt is made to have equal emphasis on material processing and application aspects such that this emerging technology can be optimally positioned in the broader context of carbon‐based microfabrication.

“…The weak absorption peaks at 1752, 1659 and 705 cm −1 correspond to the symmetric stretching vibration of C=O, the -C=O- vibration and the deformation vibration of the acyl ring. These energy bands correspond to the CO-N-OC group, demonstrating that MWCNTs-COOH attached to PANI through covalent bonds [ 29 , 30 , 31 ]. The Raman spectra provide additional evidence for the growth of PANI along the MWCNTs.…”

Gas sensors have played a critical role in healthcare, atmospheric environmental monitoring, military applications and so on. In particular, flexible sensing devices are of great interest, benefitting from flexibility and wearability. However, developing flexible gas sensors with a high sensitivity, great stability and workability is still challenging. In this work, multi-walled carbon nanotubes (MWCNTs) were grown on polydimethylsiloxane (PDMS) films, which were further modified with polyaniline (PANI) using a simple chemical oxidation synthesis. The superior flexibility of the PANI-MWCNTs/PDMS film enabled a stable initial resistance value, even under bending conditions. The flexible sensor showed excellent NH3 sensing performances, including a high response (11.8 ± 0.2 for 40 ppm of NH3) and a low limit of detection (10 ppb) at room temperature. Moreover, the effect of a humid environment on the NH3 sensing performances was investigated. The results show that the response of the sensor is enhanced under high humidity conditions because water molecules can promote the adsorption of NH3 on the PANI-MWCNTs/PDMS films. In addition, the PANI-MWCNTs/PDMS film sensor had the abilities of detecting NH3 in the simulated breath of patients with kidney disease and the freshness of shrimp. These above results reveal the potential application of the PANI-MWCNTs/PDMS sensor for monitoring NH3 in human breath and food.

“…SPCE provide more possibilities for the study of electrochemical sensors, and sensors with different detection effects can be obtained by modifying different materials. [21][22][23] Paracetamol (PA) is one of the most commonly used antipyretic and analgesic drugs in the medical field, and it is also an excellent free state internal reference probe for constructing a ratiometric sensor in the electrochemical field. 24 It has been reported that it can be synthesized using ultrasound.…”
