Practical sensing applications such as real‐time safety alerts and clinical diagnoses require sensor devices to differentiate between various target molecules with high sensitivity and selectivity, yet conventional devices such as oxide‐based chemo‐resistive sensors and metal‐based surface‐enhanced Raman spectroscopy (SERS) sensors usually do not satisfy such requirements. Here, a label‐free, chemo‐resistive/SERS multimodal sensor based on a systematically assembled 3D cross‐point multifunctional nanoarchitecture (3D‐CMA), which has unusually strong enhancements in both “chemo‐resistive” and “SERS” sensing characteristics is introduced. 3D‐CMA combines several sensing mechanisms and sensing elements via 3D integration of semiconducting SnO2 nanowire frameworks and dual‐functioning Au metallic nanoparticles. It is shown that the multimodal sensor can successfully estimate mixed‐gas compositions selectively and quantitatively at the sub‐100 ppm level, even for mixtures of gaseous aromatic compounds (nitrobenzene and toluene) with very similar molecular structures. This is enabled by combined chemo‐resistive and SERS multimodal sensing providing complementary information.

“…Zirconia (ZrO 2 ) has outstanding chemical and physical properties that include high surface area, mechanical strength, superior ionic conductivity, high thermal stability and defect induced conductivity. [23,24] Many electro-catalysts in combination with zirconia are explored such as carbon paste electrode modified with zirconia choline chloride-gold nanoparticles, [25] tape casted sodium beta alumina and yttria stabilized zirconia heterojunction, [26] zirconia modified with Poly 3,4-ethylenedioxythiophene sensor, [27] and etc.,have been prepared for improved performance of the sensor. Presence of zirconia along with electro-active catalyst not only improves the strength, but also high surface area and surface active sites.…”

Selective and highly sensitive detection of nitrite is always a challenge for electrochemist for the administration of nitrite in water and food samples. In this regard nanostructured materials are crown choice. In the present investigation, we have prepared uniformly ordered hybrid Mn 3 + /4 + : ZrO 2 nanoganitrus via hydrothermal method, characterized by XRD, BET, SEM, TEM and XPS to understand the structural and morphological features of the material and used for the electrocatalytic determination of nitrite. The preparation process resulted in the formation of nanoganitrus heterostructures with honeycomb arrangement. High surface area, ganitrus structure and hybrid Mn 3 + /4 + in the material was correlated to its robust electrochemical performance. Thus, prepared sensor showed highly selective and sensitive determination of nitrite with a good linear range of 250 μM to 10,000 μM with correlation coefficient of 0.998 and a sensitivity of 38.8 μAmM À 1 cm À 2. The limit of Detection of nitrite sensing system was 93 μM at a signal to noise ratio of 3. Also, the sensor showed prominent reproducibility, good stability, anti-interference performance and also the prepared sensor was successfully used for the detection of nitrite in real samples.
