This work presents a new approach with details on the integrated platform and hardware architecture for nanorobots application in epidemic control, which should enable real time in vivo prognosis of biohazard infection. The recent developments in the field of nanoelectronics, with transducers progressively shrinking down to smaller sizes through nanotechnology and carbon nanotubes, are expected to result in innovative biomedical instrumentation possibilities, with new therapies and efficient diagnosis methodologies. The use of integrated systems, smart biosensors, and programmable nanodevices are advancing nanoelectronics, enabling the progressive research and development of molecular machines. It should provide high precision pervasive biomedical monitoring with real time data transmission. The use of nanobioelectronics as embedded systems is the natural pathway towards manufacturing methodology to achieve nanorobot applications out of laboratories sooner as possible. To demonstrate the practical application of medical nanorobotics, a 3D simulation based on clinical data addresses how to integrate communication with nanorobots using RFID, mobile phones, and satellites, applied to long distance ubiquitous surveillance and health monitoring for troops in conflict zones. Therefore, the current model can also be used to prevent and save a population against the case of some targeted epidemic disease.

O desenvolvimento de nanobiosensores é um dos avanços mais recentes no campo da nanotecnologia. A investigação sobre nanobiosensores ópticos com dimensões submicrométricas tem aberto novos horizontes para as medições intracelulares. Aproveitando as propriedades únicas dos nanomateriais, nanobiosensores mais rápidos e sensíveis podem ser desenvolvidos. Além de serem sensíveis e rápidos, os estudos de nanobiosensores têm voltado seus esforços para o desenvolvimento de sensores baseados em nanomateriais que são acessíveis, robustos e reprodutíveis. Os nanobiosensores estão equipados com sondas biorreceptoras imobilizadas, por exemplo, anticorpos, substrato de enzima. A excitação por laser é transmitida para o sistema fotométrico na forma de sinal óptico (fluorescência). Os nanobiosessores poderão revolucionar no futuro o diagnóstico de doenças.

“…The coding gain further improves the Q-factor [4]. Since the wireless microvalve is primarily intended for biomedical applications its important to make the device as small as possible which calls for increase in interrogating frequency, however, the higher the frequency is, the higher is the attenuation of the wave travelling in tissue [2]. As a result there is a trade-off between the penetration depth and device size for a given maximum excitation power.…”

Improving the security and actuation of wireless controlled microvalve

A wireless microvalve would have a wide range of applications, including biomedical applications such as fertility control and nano-litre drug delivery. Arguably the most important aspect for such a device is a secure method to actuate the valve, such that it is not actuated through the spectrum of electromagnetic radiation already present in the surrounding environment. Additionally, many of the possible applications are sensitive to electromagnetic (EM) radiation so the device should be designed to only require the minimum amount of EM input to actuate the valve. To overcome this problem, we propose the use of a coded interdigital transducer (IDT) to respond only to a coded signal. For the wireless microvalve to be useful in biomedical applications, the IDT's response to a specifically coded RF signal must be much greater than its response to another coded RF signal, even if the two codes are very similar, i.e. improve the signal ratio of the device. In this research we demonstrate a number of code sequences that have a correlation function such that the peak response is unique and can be used to provide a high signal-to-noise ratio (SNR) surface acoustic wave. That results in a unique activation of the device when the interrogating RF signal code sequence matches the stored code sequence in the device. Also we will investigate the trade-off between the needed code length to ensure secure operation and the area constrain of the device within the context of biomedical application. For this purpose, the IDT is modelled as a pulse compression filter, which correlates the input signal with a stored replica.Keywords: microvalve, SAW, IDT, biomedical applications, coded actuators INTORDUCTIONA wireless, battery less microvalve uses no direct electrical power but makes use of the interrogating signal to provide the needed actuation. Such a device can be placed in an inaccessible location thus opening up new host of applications such as flow regulation, on/off switching and sealing of liquids, gases or vacuums [1][2][3]. For this purpose we utilise an IDT configuration with the SAW device. The IDT transforms this incoming RF signal from the antenna to a SAW and vice versa. Wireless interrogation of the device is possible by connecting the IDT to an antenna. The SAW generated by the IDT propagates along the piezoelectric substrate. The principles of SAW and the SAW generation mechanism in the microvalve are discussed in a previous publication [3]. The high energy density and small size make SAW devices attractive for actuator applications. But on the other hand the device requires a high input power level to drive it, hence it is important to have an efficient antenna design and ensure that the device will only trigger to a uniquely coded RF signal. Both of these objectives can be achieved by modelling the IDT as a pulse compression filter thus combining the narrowband, high Q-factor operation of a band pass filter with a coded reception scheme. The coding gain further improves the Q-factor [4]. Since the wirel...
