    There is already a significant time, but it gives the sensation of an extremely short period – nanotechnology has become one of the most promising scientific hopes in innumerable human domains. Now the hope became reality. Countless scientific studies in several areas of knowledge have been made since the nanoscale emergence, carrying their contribution to the nanoscience development. The recent researches in this field allowed the union of interests among several areas, such as physical sciences, molecular engineering, biology, biotechnology, and medicine, contributing to the investigation of biosystems at a nanoscale. This chapter begins by discussing nanotechnology in a general way. Then nanotechnology and its applications in industry, in electronics, and in medicine are presented, and some discussion is proposed in order to define the boundaries for the advances in those areas. In the end, nanotechnology is discussed in terms of ethics and the borders that nanotechnology applications must satisfy, and concluding notes are presented, highlighting the results of the analysis. Important considerations are made about the close connection between ethics and the nanotechnology and the effects over the society and values. Some future directions for the research are suggested.info:eu-repo/semantics/acceptedVersio

    Modeling, Simulation and Validation of a Bio-Inspired and Self-Powered Miniature Pressure Sensing System for Monitoring Cerebral Intra Aneurysmal Pressure

    Intracranial aneurysm rupture is one of the main cause for the intracranial bleeding. A brain aneurysm is an abnormal focal bulging of the arteries in the brain. As an aneurysm grows, its wall becomes thinner and weaker, which is more prone to rupture. Rupture of the intracranial aneurysm leads to releasing blood into the spaces around the brain - called a subarachnoid hemorrhage (SAH). 10 to 15% of the patients with subarachnoid hemorrhage die immediately. To prevent aneurysmal bleeding, it is essential to seclude the aneurysm from the blood circulation. This can be done with open craniotomy with microsurgical clipping and minimally invasive endovascular surgery. One of endovascular surgical technique is to place stent/flow-diverter across the neck of the aneurysm. The stent across the aneurysm reduces the flow within the aneurysm and help to form the thrombus within the aneurysm. However, approximately 3% people with the flow- diverter treatment may have delayed aneurysm bleeding after the stent placement. Short-term studies show that the stents can reduce the flow within the aneurysm but not the pressure. Currently there is no other device available to measure the intracranial intraaneurysmal pressure. This work is on designing a bio-inspired, self-powered, passively operated PVDF pressure sensor that can be deployed within the aneurysm, during flow diverting endovascular treatment that is very sensitive to small changes in pressure. The design utilizes the ear mechanics benefits by consisting of the circular vibrating membrane which vibrates based on the intraaneursymal pressure changes. This mimic the tympanic membrane part of the ear. The design continues to follow the middle ear’s mechanical advantage mechanism by incorporating the surface area increase and leverage mechanism, by the other side of the vibrating membrane been connected to three pole-links structures similar to the three bones of the middle ear to perform the middle ear’s amplification mechanism. This is followed by a composite cantilever beam structure with the sensor strips, which mimics the coiled cochlea of the inner ear in elongated form. This piezoelectric sensor strips are responsible for the passive mechanoelectrical conversion and generation of electric voltage, for the intraaneursymal pressure change application. Simulation, experiments and analysis at every level are done. Simulation and experimental result correlate and match the modeling

    This study aimed to present a new model to develop and expand nanotechnology in particular in the field of medicine.  The subject under study focus on the control design of nano-robots for bio-molecular assembly manipulation, and use of evolutionary factors as a suitable method to gain the adaptive properties for proposed model is needed. Moreover, the study use of neural networks as the most practical method for the optimization problem of robot motion using a sensor based system. Thus, the study proposes a useful method within advanced graphics simulation for nano-assembly automation with its focus on an applied model for nano-medicine. Therefore, the study results should provide a great impact for effective design of control instrumentation, helping in the development of nanotechnology. The presented nano-robot model is required to survive and interact with a complex environment. Furthermore the nano-robot has to consider a pre-defined set of tasks both in a competitive scenario and in a collective environment. Nano-robot in a three-dimensional environment monitors organ inlets’ nutritional levels, and assembling new biomolecules into that have to be delivered to the organ inlets with higher priority during each moment of our dynamic simulation. The nano-robot must avoid fuzzy obstacles, and must with proper time and manner react in real time for an environment requiring continuous control. In order to achieve the most pre-programmed set of behaviors the nano-robot uses a local perception through simulated sensors to effectively interact with the surrounding environment. The development of new concepts on nano-mechatronics and automation theory is focused on the problem of molecular machine systems. Finally a novel adaptive optimal method is described and the model validation through the application of nano-robot control design for nano-medicine confirmed
