摘要： Systems and methods for detecting the presence of biomolecules in a sample using biosensors that incorporate resonators which have functionalized surfaces for reacting with target biomolecules. In one embodiment, a device includes a piezoelectric resonator having a functionalized surface configured to react with target molecules, thereby changing the mass and/or charge of the resonator which consequently changes the frequency response of the resonator. The resonator's frequency response after exposure to a sample is compared to a reference, such as the frequency response before exposure to the sample, a stored baseline frequency response or a control resonator's frequency response.

摘要： An FBAR device may be chemically functionalized by depositing an interactive layer so that targeted chemicals are preferentially adsorbed. Such miniaturized chemical sensors may be combined with wireless network technology. For example, a chemical sensor may be integrated in a cell phone, PDA, a watch, or a car with wireless connection and GPS. Since such devices are widely populated, a national sensor network may be established. Consequently, a national toxicity map can be generated in real time. Detailed chemical information may be obtained, such as if a chemical is released by a source fixed on ground or by a moving object, or if is spread by explosives or by wind and so on.
