摘要:
A method for making a patterned SiO2 films over TiO2 (Si02/Ti02) under ambient atmospheric conditions, including room temperature, through photo and chemical reactions. The method is simple, convenient and can be performed in a short period of time, typically less than two hours. The patterned TiO2 film is fabricated through photo-irradiation of a photosensitive organic-titanium film using a mask. Silica particles are generated from silicate solution by adjusting pH values to 10 to 8 with hydrochloric acid. The pre-deposited TiO2 film has a strong attraction for the SiO2 particles, leading to the instant formation of SiO2 film over the TiO2 film. The silica films are also amino-silylated with 3-aminopropyltriethoxysilane toward applications such as patternable, location-specific silica-based separation and purification.

An autonomous genosensor apparatus and methods for use are provided for the field detection and analysis of ambient chemical, biochemical, biologic, biogenetic, and radiologic materials under field conditions in fluid or gaseous environments, such as marine or aquatic environments or industrial processes. Autonomous genosensors provide integral, self contained units which automatically extract environmental samples, prepare those samples for analytical studies, analyze those samples using studies such as DNA or biomarker analysis, and store or transmit the data produced to a remote computer or computer network. Autonomous genosensors may be used as freestanding units, or may be networked and controlled through a remote computer network.
