    Abstract: A measurement method for quantitatively measuring amounts of at least two varieties of microorganisms in a test sample. The measurement method includes: producing a first sample by performing step dilution and division of the test sample; producing a second sample by amplifying nucleic acids of the microorganisms in the first sample; and performing hybridization of the second sample in a probe array including spots to which probes having complementary sequences to target nucleic acids specific to each of the varieties of the microorganisms are fixed; and identifying the varieties of the microorganisms based on light emission from the spots where the hybridization is performed and quantitatively measuring amounts of the microorganisms by a most probable number method.

    Abstract: A biosensor using an exceptional point is disclosed. A biosensor according to one embodiment of the present disclosure includes: a biosensing unit configured to output wavelength-separated optical signals from destruction of an exceptional point resulting from attachment of biomolecules; a detection unit configured to convert the wavelength-separated optical signals into wavelength-separated electrical signals; an analysis unit configured to measure a beat frequency resulting from the wavelength-separated electrical signals; and a determination unit configured to determine a wavelength difference resulting from the beat frequency, thereby determining the amount of the biomolecules therefrom.

    Abstract: A system for measuring a membrane potential is disclosed. The system comprises a photoacoustic probe including a laser and an ultrasound transducer. The laser is configured to emit a light signal at one or more wavelengths to a neuronal cell. The neuronal cell may comprise a voltage-sensitive protein configured to absorb the light signal in a voltage-dependent manner. The ultrasound transducer is configured to receive a photoacoustic signal from the voltage-sensitive protein in response to absorbing the light signal. The system further comprises a processor configured to receive the photoacoustic signal from the ultrasound transducer and calculate a membrane potential of the neuron based on the photoacoustic signal. Methods of measuring a membrane potential and biomaterials related to the voltage-sensitive protein are also disclosed herein.
