A highly selective liquid membrane nitrite microsensor based on the hydrophobic ion-carrier aquocyanocobalt(III)-hepta(2-phenylethyl)-cobrynate is described. The sensor has a tip diameter of 10 to 15 (mu)m. The response is log-linear in freshwater down to 1 (mu)M NO(inf2)(sup-) and in seawater to 10 (mu)M NO(inf2)(sup-). A method is described for preparation of relatively large polyvinyl chlori...

A conductometric microsensor for measuring methanol vapor was conceived, based on electrospun composite nanofibers of polyvinyl chloride (PVC) doped with nickel phthalocyanine (NiPc) deposited interdigitated electrodes (IDEs) as transducers. The nanofiber’s shape, structure, percent atomic content and thermal properties were studied. sensor showed good sensitivity (505µS.cm?1.(v/v)?1), low limi...

Meiofauna (invertebrates that pass through a 1-mm mesh sieve, but are retained on 40-µm mesh) represent the most abundant and diverse animal group Earth, empirical evidence of their role in benthic respiration, production carbon cycling across ecosystems is not well documented. Moreover, how meiofauna respond to changing oxygen conditions poorly understood. We further developed an incubation sy...

This paper presents a comprehensive study of the self-assembly dynamics and the biosensing efficacy of Tobacco mosaic virus-like particle (TMV VLP) sensing probes using an impedimetric microsensor platform. TMV VLPs are high surface area macromolecules with nanorod structures constructed from helical arrangements of thousands of identical coat proteins. Genetically modified TMV VLPs express bot...
