Javier Maira, Javier Etxabe, Pedro A Serena
Nanoscience and nanotechnology made their appearance in the scientific scene at a time when both the economy of Spain and the Spanish Research and Innovation System were experiencing strong growth. This circumstance resulted in a remarkable development of nanoscience and nanotechnology especially in universities and public research institutions such as the Spanish National Research Council (Consejo Superior de Investigaciones Científicas - CSIC). However, this development in academia has not been reflected in a similar increment in the transfer of knowledge to the productive sector despite several efforts and initiatives were launched...

Michael Z Hu, David W DePaoli, Tanya Kuritz, Ogbemi O Omatete
We present a "bottom-up" fabrication approach to first grow a new class of inorganic (silica) long hair-like microfibrils or microwires and then to form monolithic solid pellet that contains parallel arrays of bundled microfibrils with a controlled orientation. During the sol-gel solution processing, reactive precursor species are utilized as molecular "building blocks" for the field-directed assembly growth of microfibrils driven by an electric field of pulsed direct current (dc) with controlled frequency...

Lei Wang, Sidi Gong, Cihui Yang, Jing Wen
BACKGROUND: The necessity to handle mechanical functionality at nanoscale has recently motivated the prosperity of the nanoelectromechanical systems (NEMs). The fabrication of NEMS strongly depends on the so-called "topdown" techniques that are however limited by the resolution of electronbeam lithography. Meanwhile, the size of the NEMS needs to be shrunk continuously in order to further enhance the system performance. As a result, current research interest has been dedicated to "bottomup" techniques or even a hybridization of two aforementioned approaches, leading to the presence of the nanowire-based NEMs...

DNA sequencing is one of the crucially important tasks in the fields of genetics and cellular biology, which is benefiting from nanotechnology. DNA carries genetic information and sequencing it in a quick way helps researchers in achieving essential goals, including personalized medicine. Solid state nanopores potentially can offer more durability, in sequencing biomolecules, over the proteinbased nanopores. In recent years, various ideas are introduced towards the goal of fast and low cost sequencing. In this review article recent advances presented in journal articles as well as patents in this field, including sequencing methods, membrane materials and their fabrication techniques, drilling methods, and biomolecule translocation speed control ideas are investigated...
