Aroma sensing and indoor air monitoring by quartz crystal resonators with sensory films prepared by sputtering of biomaterials and sintered polymers

Classification and characterization of atmospheric VOCs based on sorption/desorption behaviors of plasma polymer films

“…Moreover, water vapor tends to adsorb onto the surface of the PPF and to diffuse into the PPF. We have reported that the response curves of these PPF-coated QCRs to an ambient air have been closely correlated with the sensorgram of a humidity sensor in the passive measurement [12,13]. As shown in Fig.…”

“…In such cases, the measurement is carried out under dry and constant-flow conditions without the influence of ambient air [10,11]. However, the PPF-coated QCRs are so sensitive that they are affected by humidity in practical use [12,13]. In terms of practical applications, we must overcome this fluctuation problem posed by PPF-coated QCR sensors operating under ambient conditions.…”

Nanocomposite and Nanostructured Carbon-based Films as Growth Substrates for Bone Cells

“…Plasma polymer films with immobilized heparin can serve as hemocompatible surfaces preventing blood coagulation . Another broad and advanced application of plasma polymers is the construction of biosensors (Seyama et al, 2004;Chu et al, 2009). As for interaction with anchorage-dependent cells, plasma polymer films can be constructed as repulsive or attractive for cells.…”

Creation of a fiber optic based biosensor for air toxicity monitoring

“…Smart gas sensing systems, i.e. electronic noses, comprising an array of gas sensors [7][8][9], quartz-crystal resonators [10] and other sensor techniques may meet these requirements for indoor air monitoring. However, the main disadvantage of all these applications is their inability to measure the biological effects of tested air pollutants for various types of toxicities (e.g.…”
