Nano-scale technologies as tools for transformation of traditional materials in functional and smart materials

ABSTRACTHigh performance biosensors are urgently needed from medical diagnosis, to food safety/security, to the war on bio-terrorist. The smart materials play an important role in the development of high performance sensor platform. Biosensors based on microcantilevers have very high sensitivity. The microcantilevers made of different materials, such silicon, piezoelectric and magnetostrictive materials, are discussed and compared in this paper. The magnetostrictive-based microcantilevers exhibit the best performance among all microcantilevers. A new sensor platform – magnetostrictive particles (MSPs) – is reported. The advantages of MSPs over microcantilevers are experimentally demonstrated. The MSPs are wireless/remote sensors, which makes it is possible to employ the MSP-based biosensors in different environments/media. The fabrication of MSPs in micro to nano-scale is reported. Compared with the microcantilevers, MSPs exhibit a better mass sensitivity and a higher Q value, which make the MSPs a much higher overall sensitivity.

Research Questions

Flexible formworks are dominantly used for concrete constructions. These constructions become rigid after curing and their form cannot be changed, also their color or translucency is stable during usage period; i.e. these constructions are not flexible. On the other hand, in order to satisfy new architectural requirements the necessity of flexibility and smartness is undeniable for the construction.The questions of this paper are: How smartness can be added to rigid structures? What are the roles of nano-flexible formworks to turn non-flexible structures into flexible ones? To answer the research questions, descriptive - analytical research method has been adopted and empirical data gathered to feed inference mechanism. Our investigation shows that if the flexible formwork has been made by smart materials which are changeable in nano-scale, and the formwork is left on the structure even after curing, it would act as a nano-flexible skin for the structure and would satisfy some architectural requirements in nano-scale.
