“…[372] Alam et al reported the fabrication of rGO/CNP hybrid IR photodetector that could detect human body IR radiation under ambient conditions. [120] Figure 15b shows the comparison of I-V characteristics between bare rGO device and rGO/CNP hybrid device under dark and under IR radiation from a hand kept away at 2 cm from the device at room temperature. The rGO/CNP hybrid photodetector clearly exhibited much higher photoresponse to IR radiation compared to bare rGO device, showing its promising potential as IR sensing applications.…”

Two‐dimensional (2D) materials have attracted tremendous research attention in recent days due to their extraordinary and unique properties upon exfoliation from the bulk form, which are useful for many applications such as electronics, optoelectronics, catalysis, etc. Liquid exfoliation method of 2D materials offers a facile and low‐cost route to produce large quantities of mono‐ and few‐layer 2D nanosheets in a commercially viable way. Optoelectronic devices such as photodetectors fabricated from percolating networks of liquid‐exfoliated 2D materials offer advantages compared to conventional devices, including low cost, less complicated process, and higher flexibility, making them more suitable for the next generation wearable devices. This review summarizes the recent progress on metal–semiconductor–metal (MSM) photodetectors fabricated from percolating network of 2D nanosheets obtained from liquid exfoliation methods. In addition, hybrids and mixtures with other photosensitive materials, such as quantum dots, nanowires, nanorods, etc. are also discussed. First, the various methods of liquid exfoliation of 2D materials, size selection methods, and photodetection mechanisms that are responsible for light detection in networks of 2D nanosheets are briefly reviewed. At the end, some potential strategies to further improve the performance the devices are proposed.

“…Due to the mechanical, thermal, optical, electronic and optoelectronic properties, graphene has been considered as a potential candidate for future generation bioimaging sensors and biomedical applications. [ 85 ] The introduction of functional groups on the graphene plane has improved the versatility and inertness, yielding better optical, electronic and targeting properties. Covalent modification, such as the addition of hydroxyl, carboxyl and epoxy groups, and noncovalent interactions including π−π interaction, hydrogen bonding, and van der Waals forces have prevented graphene from aggregation.…”

This review aims to review the biomedical applications of nanocarbons to various cardiovascular devices including implantable scaffolds, patches, and stents against coronary artery diseases (CAD). The clinical applications of nanocarbons in cardiac tissue engineering, cardiomyocyte supporting implants, biosensors for cardiovascular biomarkers, bioimaging and monitoring of pathological conditions of CAD are addressed. In addition, the current challenges in minimizing the toxicity of nanocarbon materials and alleviating techniques are discussed from a clinical perspective. A novel fabrication approach for nanocarbons in cell-laden cardiovascular stents is a promising regenerative means for the treatment of damaged infarction in CAD.
