• atomic force microscopy nanolithography methods, nanomachining and nano-oxidation, are employed. A single titanium nanowire (NW) is created first along with contact electrodes and a single titanium oxide ND is subsequently produced in the NW. Gas sensing is realized by the photo-activation and the photo

• potential application of single metal oxide NDs for gas sensing with a performance that is comparable with that of metal oxide nanowire gas sensors.

• -assisted approaches including photo-activation [12][13][14][15][16][17][18][19][20][21] and photo-recovery [22][23] have been shown effective to enable gas sensing at room temperature. The sensing material in a semiconducting metal oxide sensor is commonly synthesized by a bottom-up approach, such as

However, the distribution of both protein types in the early stage of the desmin filament formation, i.e., oligomers and unit length filaments (ULF), respectively, is still not known
