Provided are positively charged nanoparticles and use thereof. According to the nanoparticles of an aspect, cucurbituril may limit electrostatic attraction between a guest for cucurbituril and a metal salt, thereby generating nanoparticles with a uniform size. Accordingly, the nanoparticles may have an effect of being capable of efficient intracellular gene delivery.

Positively charged nanoparticles, use thereof, and preparation method thereof

Provided is a field-effect transistor that can reduce noise, be produced by a simplified manufacturing method, and also have a plurality of active patterns and gate patterns designed to be combinable according to a detection purpose. The field-effect transistor includes a lower silicon layer and a buried oxide layer disposed on the lower silicon layer; an active pattern disposed on the buried oxide layer and including a channel region, a source region, and a drain region; a gate pattern disposed on the active pattern to at least partially overlap the active pattern; a source electrode disposed in direct contact with the source region on the active pattern, and a drain electrode disposed in direct contact with the drain region on the active pattern; and a gate insulating film disposed between the active pattern and the gate pattern.
