Here we review recent results on the synthesis of single-crystalline metal oxide
nanomaterials and their integration in resistive gas sensing devices. Emphasis is put on the
integration of such nanomaterials in a wide spectrum of transducing platforms, ranging from
standard ceramic to silicon MEMS or flexible polymeric. Some strategies for achieving
higher selectivity are discussed, which are followed by a discussion on the development of
advanced operation techniques for achieving more stable and faster response to gases …
