发明名称 Nano sensing of temperature using equal intensity double plasmon resonance (EIDPR)
摘要 Technologies are generally described for providing and using a material including: a template molecule; a first cluster of one or more nanoparticles located at a first site on the template molecule; and a second cluster of one or more nanoparticles located at a second site on the template molecule and spaced apart from the first cluster. In some embodiments, the first and second clusters of nanoparticles exhibit a plasmon resonance having a first resonant peak and a second resonant peak.

主权项 1. A method of detecting a temperature of an environment, the method comprising: introducing a material to the environment, the material comprising: a template molecule; wherein the template molecule is tryptophan, tryptophan alkyl ester, or methionine;a first cluster of two or more silver nanoparticles located at a first affinity site on the template molecule, wherein the first affinity site includes at least one of: a nitrogen atom or a sulfur atom; anda second cluster of two or more silver nanoparticles located at a second affinity site on the template molecule and spaced apart from the first cluster, wherein the second affinity site includes at least one of: a nitrogen atom or a sulfur atom;wherein the template molecule, the first cluster of two or more silver nanoparticles, and second cluster of two or more silver nanoparticles form a molecular sandwich structure; irradiating the material so as to cause the first cluster of silver nanoparticles to exhibit a plasmon resonance having a first resonant peak, and the second cluster of silver nanoparticles to exhibit a plasmon resonance having a second resonant peak; wherein the first resonance peak has a first absorbance value, the second resonance peak has a second absorbance value, and the first and second absorbance values differ by less than 25%; detecting at least one characteristic of the plasmon resonance of the material; and determining information indicative of the temperature of the environment based on the at least one detected characteristic of the plasmon resonance of the material; wherein the temperature is from about 0° C. to about 100° C.
