“…This method employs soft and elastomeric materials as well as hydrogels to manufacture nanoand microscale 3D structures (with width and depth below 100 μm) [211,212] for finding biological applications based on printing and molding. [213,214] Sealed cell-laden agarose hydrogels with heating molded gel-surface microfluidic channels were produced with soft-lithographic approaches (Figure 8A). [201] Interestingly, Wang et al [167] developed a strategy to generate 3D microchannels by making use of a soft-lithography method.…”

Cartilage degeneration is among the fundamental reasons behind disability and pain across the globe. Numerous approaches have been employed to treat cartilage diseases. Nevertheless, none have shown acceptable outcomes in the long run. In this regard, the convergence of tissue engineering and microfabrication principles can allow developing more advanced microfluidic technologies, thus offering attractive alternatives to current treatments and traditional constructs used in tissue engineering applications. Herein, the current developments involving microfluidic hydrogel‐based scaffolds, promising structures for cartilage regeneration, ranging from hydrogels with microfluidic channels to hydrogels prepared by the microfluidic devices, that enable therapeutic delivery of cells, drugs, and growth factors, as well as cartilage‐related organ‐on‐chips are reviewed. Thereafter, cartilage anatomy and types of damages, and present treatment options are briefly overviewed. Various hydrogels are introduced, and the advantages of microfluidic hydrogel‐based scaffolds over traditional hydrogels are thoroughly discussed. Furthermore, available technologies for fabricating microfluidic hydrogel‐based scaffolds and microfluidic chips are presented. The preclinical and clinical applications of microfluidic hydrogel‐based scaffolds in cartilage regeneration and the development of cartilage‐related microfluidic chips over time are further explained. The current developments, recent key challenges, and attractive prospects that should be considered so as to develop microfluidic systems in cartilage repair are highlighted.

“…Many researchers have attempted to enhance the PVATF sensors with various optimization techniques in order to attain the best performance of the sensor by improving the sensing capabilities or characteristics, such as dielectric properties. 6,118 For instance, Karami enhanced the gas sensing characteristics of a PVA-based CdO-ZnO nanocomposite as a carbon monoxide (CO) gas sensor through optimization of the sol-gel pyrolysis method synthetic conditions. The optimized parameters included concentrations of Zn(NO 3 ) 2 , Cd(NO 3 ) 2 , and PVA, solvent composition, and pyrolysis temperature by the "one at a time" method.…”

Polyvinyl alcohol (PVA) thin films (PVATFs) have recently exhibited different applications in various fields, such as biomedical, optical, and energy storage. One of their outstanding applications has been known as sensor devices for various physical parameters, such as pH, pressure, gas, chemicals, strain, and humidity measurements. In this paper, after a brief review of the PVATFs biomedical, optical, and energy applications, their role as sensors is discussed in more detail. Afterward, the main preparation methods of the PVATFs sensors, for example, spin and dip coating, chemical bath deposition, and electrodeposition are surveyed. Eventually, the characterization methods of the fabricated PVATF sensors, along with their optimization techniques have been presented.Highlights Various applications of polyvinyl alcohol thin films (PVATFs) are presented. One of their main applications as sensor devices is discussed in more detail. PVATF sensors fabrication, characterization, and optimization are surveyed.

In this chapter, we present an overview of graphene derivatives and their nanocomposites for the development of biosensors. The importance of graphene nanocomposites in sensing is also highlighted. They have received much attention due to their distinctive chemical and physical properties. The surface, mechanical, optical, thermal, electronic, and other properties of graphene are also reviewed. Additionally, some graphene derivatives, such as GO and rGO, are described. Some common synthesis methods of graphene by top-down and bottom-up approaches, including mechanical exfoliation, chemical synthesis, chemical vapor deposition, pyrolysis, and other methods, are summarized. Finally, the chapter focuses on some applications of graphene nanocomposite-modified electrodes in sensing applications.
