Advantages and disadvantages of 1D nanostructures.

Structure	Advantage	Disadvantage	References
nanofibers	short recovery time	minimal response, long response time	[95,110,115,144,280–281]
hollow nanofibers/nanotubes	high sensitivity, short response time	long recovery time	[78,102,119,129,133,282]
nanowires	high sensitivity, low detection limit	long response/recovery time	[135]
