| Description
| - Nanotechnology is one of the most popular technologies being used nowadays in manufacturing various high tech devices. The main reason behind this is nanotechnology makes devices more efficient with better performance by changing their physical compositions. SnO2 has been used extensively in semiconductor gas sensors for detecting a wide range of different gases. The aim of the paper is to investigate gas sensing properties of self-assembled multilayers based on SnO2 nanoparticles. Quartz Crystal Microbalance (QCM) sensors used in this study in contrast to semiconductor sensors are based on the mass change. Layers of SnO2 nanoparticles were grown using layer-by-layer self-assembly technique. A substrate was alternately immersed in poly(diallyldimethylammonium) chloride (PDDA) and in SnO2 colloidal dispersion in water. Sensing properties of these layers to various gases were examined. The thicknesses of layers created during self-assembly deposition process were evaluated from a resonant frequency shift of the QCM sensor. The surface morphology was studied by atomic force microscopy (AFM). The number of self-assembling steps has an influence to the sensor sensitivity. The developing QCM sensors based on self-assembled technique are inexpensive, easy to make and works at room temperature.
