“…With various structures and different test methods, the detection range of certain kind small molecules is quite wide (from around 10 -11 M to 1 M). Besides the molecules listed in the table, other small biomolecules such as quercetin ), isoquercitrin, baicalin (Liu et al 2014d), cholesterol (Agnihotri et al 2015) and ATP (Vanegas et al 2015) have also been detected by electrochemical biosensors in recent years.…”

“…The mixed solution was stirred and diluted in phosphate buffered saline (PBS) to form β-CD/rGO hybrid nanosheets that can be used in the sensing of cholesterol (Agnihotri et al 2015). Besides CDs, there are also many other organics that can be composited with rGO for the detection of other biomolecules.…”

“…Zhang et al designed PSSA‐g‐PPY functionalized graphene to detect H 2 O 2 , which can also be used to detect hypoxanthine in fish samples 129. In addition, other small biomolecules such as quercetin,130 isoquercitrin, baicalin,131 cholesterol132 and ATP133 can also be detected with graphene film‐based biosensors. However, while introducing them into clinical application, the graphene film‐based biosensor system must be further improved for simplified, reasonable cost and etc.…”

Humans have numerous senses, wherein vision, hearing, smell, taste, and touch are considered as the five conventionally acknowledged senses. Triggered by light, sound, or other physical stimulations, the sensory organs of human body are excited, leading to the transformation of the afferent energy into neural activity. Also converting other signals into electronical signals, graphene‐based film shows its inherent advantages in responding to the tiny stimulations. In this review, the human‐like senses and reflexes of graphene‐based films are presented. The review starts with the brief discussions about the preparation and optimization of graphene‐based film, as where as its new progress in synthesis method, transfer operation, film‐formation technologies and optimization techniques. Various human‐like senses of graphene‐based film and their recent advancements are then summarized, including light‐sensitive devices, acoustic devices, gas sensors, biomolecules and wearable devices. Similar to the reflex action of humans, graphene‐based film also exhibits reflex when under thermal radiation and light actuation. Finally, the current challenges associated with human‐like applications are discussed to help guide the future research on graphene films. At last, the future opportunities lie in the new applicable human‐like senses and the integration of multiple senses that can raise a revolution in bionic devices.

“…After the groundbreaking experiments on the two-dimensional material graphene by Nobel Laureates, Sir Andre Geim and Konstantin Novoselov [16] from the University of Manchester, graphene came into limelight in research field mainly because of its excellent electrical [18], thermal [19], and mechanical properties [20]. Graphene found widespread applications in electronics [21], bio-electric sensors [22], energy technology [23], lithium batteries [24], aerospace [25], bio-engineering [26], and various other fields of nanotechnology [27]. In 2014, 2009 research papers were published on graphene in which about 830 papers were on graphene-epoxy nanocomposites produced using solution casting technique.…”

“…The individual layers of graphene, under external loadings and thermal stresses, undergo out-ofplane wrapping [80] [81], rippling [82] [83], folding [84] [85], scrolling [86] [87], and crumpling [88] [89], making graphene suitable to enhance the toughness of polymers. Wang et al showed that wrinkle's wavelength and amplitude are directly proportional to volumetric dimensions of graphene as evident from Equation (27) and eq. (28), where λ is wrinkle wavelength, ν is Poisson's ratio, L is the length of graphene sheet, t is thickness of graphene sheet, ε is edge contraction on a suspended graphene sheet, and A is wrinkle amplitude [90].…”

Modeling and simulation allow methodical variation of material properties beyond the capacity of experimental methods. The polymers are one of the most commonly used matrices of choice for composites and have found applications in numerous fields. The stiff and fragile structure of monolithic polymers leads to the innate cracks to cause fracture and therefore the engineering applications of monolithic polymers, requiring robust damage tolerance and high fracture toughness, are not ubiquitous. In addition, when "many-parts" cling together to form polymers, a labyrinth of molecules results, which does not offer to electrons and phonons a smooth and continuous passageway. Therefore, the monolithic polymers are bad conductors of heat and electricity. However, it is well established that when polymers are embedded with suitable entities especially nano-fillers, such as metallic oxides, clays, carbon nanotubes, and other carbonaceous materials, their performance is propitiously improved. Among various additives, graphene has recently been employed as nano-filler to enhance mechanical, thermal, electrical, and functional properties of polymers. In this review, advances in the modeling and simulation of grapheme based polymer nanocomposites will be discussed in terms of graphene structure, topographical features, interfacial interactions, dispersion state, aspect ratio, weight fraction, and trade-off between variables and overall performance.
