This paper presents the evolution of diagnostic and therapeutic procedures as a process of convergence of technologies coming from different fields and involving different disciplines. In particular, it illustrates how modern surgery evolved thanks to fundamental biology knowledge; thus, with the introduction of imaging techniques intra-operatively and with the introduction of robotics, surgical procedures...
This paper describes the production of an artificial hair cell receptor based on aligned micro/nano polyvinylidene fluoride (PVDF) fibers. Suspended aligned micro/nano fiber arrays were successfully produced on an insulator film by a novel method called thermo-direct drawing procedure. Using this method, aligned micro/nano-size PVDF fibers are obtained. Some key problems such as the fabrication of...
Polymeric single layer nanosheets have been recently developed and proposed as drug-delivery systems. By spin coating deposition, the nanometric thickness can be easily controlled, and plenty of polymers can be deposed, thus obtaining biocompatible and resistant sheets. For all these reasons, the possibility to use them as drug carriers or "nanoplasters" for closing incisions (both externally...
In this paper we present a method to make cells magnetotactic by using carbon nanotubes (CNTs). The key of the method consists of a highly biocompatible dispersion of CNTs. These CNTs, once added to culture medium of neuroblastoma cells, strongly interact with the cell membrane. CNTs-conjugated cells appear to be sensitive to applied magnetic field gradient and move towards the magnetic source. A...
