“…Nano-diagnostics typically involves the use of nanostructures for labeling, tracking and detection, signal augmentation, or transformation in living beings, as well as the detection of molecules with biological activity, to accomplish rapid illness detection and point-of-care testing (POCT). The primary investigation instructions are bio-barcode assay (BCA) ( Amini et al, 2019 ), nanoparticles ( Maeda et al, 2006 ), nanofluidic array (biochip) ( Jambari et al, 2017 ), nanobiosensors ( Ijeomah et al, 2016 ), and quantum dot (QD) ( Fang et al, 2021 ), which are used for extremely sensitive sensing, multiplex and high-throughput analysis, cell detachment and non-invasive tracing of cells, labeling fluorescent, as well as nanoprobe technologies, correspondingly. To identify biomarkers associated with inflammation like interleukin-6 (IL-6) and C-reactive protein, Borse and its colleague created a lateral flow immunoassay (LFIA) approach using fluorescent cadmium telluride QDs and a double-antibody sandwich method.…”

Nanotechnology has changed science in the last three decades. Recent applications of nanotechnology in the disciplines of medicine and biology have enhanced medical diagnostics, manufacturing, and drug delivery. The latest studies have demonstrated this modern technology’s potential for developing novel methods of disease detection and treatment, particularly in orthopedics. According to recent developments in bone tissue engineering, implantable substances, diagnostics and treatment, and surface adhesives, nanomedicine has revolutionized orthopedics. Numerous nanomaterials with distinctive chemical, physical, and biological properties have been engineered to generate innovative medication delivery methods for the local, sustained, and targeted delivery of drugs with enhanced therapeutic efficacy and minimal or no toxicity, indicating a very promising strategy for effectively controlling illnesses. Extensive study has been carried out on the applications of nanotechnology, particularly in orthopedics. Nanotechnology can revolutionize orthopedics cure, diagnosis, and research. Drug delivery precision employing nanotechnology using gold and liposome nanoparticles has shown especially encouraging results. Moreover, the delivery of drugs and biologics for osteosarcoma is actively investigated. Different kind of biosensors and nanoparticles has been used in the diagnosis of bone disorders, for example, renal osteodystrophy, Paget’s disease, and osteoporosis. The major hurdles to the commercialization of nanotechnology-based composite are eventually examined, thus helping in eliminating the limits in connection to some pre-existing biomaterials for orthopedics, important variables like implant life, quality, cure cost, and pain and relief from pain. The potential for nanotechnology in orthopedics is tremendous, and most of it looks to remain unexplored, but not without challenges. This review aims to highlight the up tp date developments in nanotechnology for boosting the treatment modalities for orthopedic ailments. Moreover, we also highlighted unmet requirements and present barriers to the practical adoption of biomimetic nanotechnology-based orthopedic treatments.

“…The miniaturization of the electronic devices over the past decade has played a major role in the electronic industry. Every stage of miniaturization results in a device which has better speed, reduced power dissipation, reduced costs, and a large number of gates on a chip [1,2]. This has been in effect due to the famous Moors law.…”

“…As the size becomes smaller, scaling the silicon MOSFET becomes harder. The limiting factors are short channel effects, ballistic transport, tunneling effect [2]. Various leakage current operations such as weak inversion current, reverse-bias p-n junction current and drain induced barrier lowering (DIBL) current have been observed in MOSFETs [9,10].…”

This paper aims to study the behavior of a Carbon Nanotube Field Effect Transistor (CNTFET) which is one of the nanoelectronic devices and a major replacement for Complementary Metal Oxide Semiconductor (CMOS) and MOSFETs, which have a wide range of short channel effects that play a prominent role in their disadvantages and, thus, have made us today to look for a better device. One such device is CNTFET which is better in terms of execution with low power consumption, faster switching speed, high carrier mobility, and very large scale integrated circuits. The channel of this transistor is surrounded by a carbon nanotube, and this paper mainly revolves around the simulation of its current-voltage (I-V) characteristics. The efficiency of this device on the whole depends on device parameters that are shown in the simulation of CNTFET, and the geometry of this device has an excellent dominance on carrier transport and permits for superior electrostatics while the gate contact wraps throughout the channel of a carbon nanotube. A carbon nanotube used for coaxial geometry has a zigzag structure and is semiconducting in nature. To ensure the efficient execution of CNTFETs as a vital part of nanoelectronic devices, chirality factor (n, m) values play an important role whose effect is shown on drain current. Further, the source/drain doping level variations that affect drain current are inspected. Also, I-V characteristics at different temperature conditions are examined which indirectly gives us an idea of the movement of electrons in this device with respect to change in temperature. Additionally, the analysis is also made to see the effect of nanotube length, coaxial gate voltage and gate thickness on I-V characteristics and also to reveal the impact of high-k materials on I-V characteristics.
