摘要： Provided is a voltage sensitive dye represented by Formula 7. Through connection of an electron donor with an electron acceptor by a triple bond, the voltage sensitive dye has a lower free rotation rate in molecular structures of the electron donor and the electron acceptor (e.g., photoisomerization), and thus fluorescence efficiency and voltage sensitivity to external electron stimulation can be improved.

摘要： A method for detecting a target biological material using DNA barcodes is provided. The method comprises: attaching a first type of probes to the surface of magnetic particles to prepare magnetic particles for isolation wherein the first type of probes are at least partially complementary to a target biological material of interest; attaching a second type of probes to the surface of polymer particles to prepare polymer particles for analysis wherein the second type of probes are at least partially complementary to the target material but are different from the first type of probes, and attaching DNA barcodes as identification codes to the surface of the polymer particles wherein the DNA barcodes are present in an amount at least three times the amount of the second type of probes, have a predetermined sequence and are labeled with a label material; reacting the magnetic particles for isolation, the polymer particles for analysis and the target material in a hybridization reaction buffer to prepare composites, each of which consists of one magnetic particle for isolation, the target material and one polymer particle for analysis; separating the composites from unreacted reactants using a magnetic separator; heating the separated composites to denature the DNA barcodes present in the polymer particles for analysis and removing the magnetic particles for isolation and the polymer particles for analysis from the composites by centrifugation to isolate the DNA barcodes; and detecting a signal generated from the label material bound to the isolated DNA barcodes.
