Nanomaterials have become very popular in technology due to their multifunctional properties which invites their usage in diversified applications. Specially, in last two decades, the application-oriented research in nanotechnology has been growing exponentially. Their potential use in preparation of structural components, energy storage devices, sensors, biomedical and biomechanical applications, etc. has shown immense opportunities for their exploration. The bloom of nanotechnology is unexpectedly moving very fast toward medical treatments, sensor technologies, self-healing materials, big data storage and processing, weather forecasting, etc. Exposing the newer ways in medical science using wearable fitness technology using tiny sensors for an intensive, accurate, and safer medical examination of living bodies is one of the important growing interests in the field of nanotechnology. Use of sensors has profound applicability in medical treatment, energy storage and harvesting, flexible manufacturing, and the development of sustainable high temperature materials. Even though the use of nanomaterials in sensing technology has introduced significant opportunities for improvement in big data analysis and whether forecasting using typical hybrid composites/nanocomposites. Table 1 comprises of some significant technological developments in diversified areas owing to the multifunctional characteristics of nanomaterials. Moreover, the potential of nanomaterials as nanofluids, nanoalloys, and self-healing materials invites researcher to explore further possibility in studying the effects of change in texture/micro-structure of the tailored materials.

Nevertheless, the expected use of nanomaterials in various high-end applications is limited due to incompetent behavior arisen by their toxic nature, compatibility issues, uniformity and repeatability in synthesis, chemical stability, and various hazardous effects to environment and living beings. Kostarelos et al. (2009) have highlighted the toxic effects of using carbon-based nanomaterials in antitumor therapies. Similarly, the effects of different nanomaterials in distortion of biological cells have been proved by various researchers (Zhang and Karn 2005; Lanone and Boczkowski 2006; Hoshino et al. 2011; Proffitt 2004; Lam et al. 2004). It has also been found that the severe effects of certain nanomaterials block the arteries in living beings and damage the central nervous system (Service RF 2004; Lam et al. 2006; Nel et al. 2006). Different aspects of challenges for realistic applications of nanotechnology are shown in Fig. 1.
