CNT-Based Nano Medicine From Synthesis to Therapeutic Application

Carbon nanotubes (CNTs) are allotropes of carbon consisting of cylindrical tubes, made up of graphite with a diameter of several nm to a length of several mm. They had extraordinary structural, mechanical, and electronic properties due to their small size and mass, high mechanical resilience, and high electrical and thermal conductivity. Their large surface area made them applicable in pharmacy and medicine and adsorb or conjugate a broad variety of medical and diagnostic agents (drugs, genes, vaccines, antibodies, biosensors, etc.). They are often used to deliver drugs directly into the cells without going through the metabolic process of body. In addition to drug delivery and gene therapy, CNTs are also used for tissue regeneration, diagnostic biosensors, chiral drug enantiomer separation, drug extraction, and drug or pollutant analysis. CNTs have recently been discovered as effective antioxidants. The ADME and toxicity of different types of CNTs have also been documented here, as well as the prospects, advantages, and challenges of this promising bio-nano technology.

Engineering Biological Tissues from the Bottom-Up: Recent Advances and Future Prospects

Tissue engineering provides a powerful solution for current organ shortages, and researchers have cultured blood vessels, heart tissues, and bone tissues in vitro. However, traditional top-down tissue engineering has suffered two challenges: vascularization and reconfigurability of functional units. With the continuous development of micro-nano technology and biomaterial technology, bottom-up tissue engineering as a promising approach for organ and tissue modular reconstruction has gradually developed. In this article, relevant advances in living blocks fabrication and assembly techniques for creation of higher-order bioarchitectures are described. After a critical overview of this technology, a discussion of practical challenges is provided, and future development prospects are proposed.

Adsorption of Oils Pollutants by Using Nano Materials

Oil and gas pollutants are among the most important and serious problems facing the world in general and the oil and gas sectors in particular. Always all legislation, international, professional and environmental organizations have been working hard to find legislation and concentrations allowed to reduce the impact and spread of these pollutants. Due to the seriousness and impact of these pollutants, great efforts are being taken to reduce these pollutants. Nano technology have been emerged as a viable option to reduced the effects of pollution facing the oil and gas industry. Porphyrin nano graphene were used for the removal of petroleum and gas pollutants through utilized adsorption process. Variety of several parameter has been done to explain the mechanism of adsorption of petroleum and gas pollutants by using porphyrin nano graphene.

Design and Analysis of Fault-Tolerant 1:2 Demultiplexer Using Quantum-Dot Cellular Automata Nano-Technology

Quantum-dot Cellular Automata (QCA) is an innovative paradigm bringing hopeful applications in the perceptually novel computing layout in quantum electronics. The circuits manufactured by QCA technology can provide a notable decrease in size, rapid-switching velocity, and ultra-low power utilization. The demultiplexer is a beneficial component to optimize the whole process in any logical design, and therefore is very important in QCA. Moreover, fault-tolerant circuits can improve the reliability of digital circuits by redundancy. Hence, the present investigation illustrates a novel QCA-based fault-tolerant 1:2 demultiplexer construct that employs a two-input AND gate and inverter. The functionality of the suggested layout was executed and evaluated with the utilization of the QCADesigner 2.0.3 simulator. This paper utilizes cell redundancy on the wire, inverter, and AND gates for designing a fault-tolerant demultiplexer. Four components (i.e., missing cells, dislocation cells, extra cells, and misalignment) were analyzed by the QCADesigner simulator. The simulation results demonstrated that our proposed QCA-based fault-tolerant 1:2 demultiplexer acted more efficiently than prior constructs regarding delay and fault tolerance. The proposed fault-tolerant 1:2 demultiplexer could attain high fault-tolerance when single missing cell or extra cell faults exist in the QCA layout.

Use of Nano Technology (Nano Gro) To Boost Productivity and Increase Pest Resistance in Okra Crop for Export in Southern Honduras.

The present study reports the effect of the nanotechnology molecule “Nano Gro” on a number of agronomical variables of okra, Abelmoschus esculentus, as well as its effect on leaf miner, white fly, Bemisia tabaci, and Spodoptera larvae attacking the crop. Most initial data was taken in a trial used for the registration of Nano Gro as an agricultural amendment in Honduras, carried in a plot worked by Juan Benito Guevara, a local okra producer farming in Las Bazas, very near the city of Choluteca, next to the Choluteca river, in Southern Honduras. However, other important data was taken on plots from different local okra companies and producers in the Choluteca area. The stimulant Nano Gro is a mixture of sulfates and elements such as Fe, Co, Al, Mg, Mn, Ni and Ag, produced at a concentration of 10-9 mol, available in the form of an oligosacharid pellet. It has OMRI certification and can be used in organic and regular agriculture. According to the Honduran distributor (Núcleo Agro), Nano Gro stimulates the plant´s natural resistance to abiotic stress, which in turn makes the plant produce growth hormones like auxins, gibberellines and cytokinines. This hormone productionmakes the use of nutrients and water more efficient, resulting in greater plant resistance, greater performance and greater quality of fruit harvested.
