Abstract: The present invention relates to near-infrared-absorbing dye-based composite particles which exhibit a photothermal effect and/or photoacoustic signal upon photoirradiation, a preparation method thereof, and a use thereof. The near-infrared-absorbing composite particles comprise: a water-insoluble salt of a near-infrared-absorbing dye, which comprises anions of the near-infrared-absorbing dye and metal cations capable of forming a precipitation product with the anions of the near-infrared-absorbing dye; and particles of a polymeric surfactant, in which a water-insoluble salt of the near-infrared-absorbing dye is supported in the hydrophobic part of the polymeric surfactant.

Abstract: A method for detecting biomaterial by means of a dye having a linear upconversion fluorescent property is provided. The method includes the steps of: i) preparing a fluorophore having a linear upconversion fluorescent property; ii) reacting the fluorophore and biomaterial to obtain a reaction complex thereof; iii) exciting the reaction complex by means of a light source having a longer wavelength than the maximum light-emitting wavelength of the fluorophore; and iv) detecting and measuring the light-emitting signal having a shorter wavelength than the wavelength of the excited light emitted from the excited reaction complex. A system and a kit for detecting biomaterial using a dye having a linear upconversion fluorescent property are also provided.

Abstract: In a compact multi molecular diagnosis system and a multi molecular diagnosis apparatus, the multi molecular diagnosis system includes a card part, a pretreatment and collector, a cleaner, a reagent unit, a heater and an optical unit. The card part moves in a rotating frame, and has a plurality of cards. The pretreatment and collector provides a collected specimen to each card of the card part. The cleaner provides a cleaning liquid to the card part, to clean the collected specimen in the card part. The reagent unit provides a plurality of diagnosis reagents to each card of the card part. The heater heats the card part absorbing the reagent, to clone a virus template. The optical unit observes the cloned virus template. The card part sequentially moves through the pretreatment and collector, the cleaner, the reagent unit, the heater and the optical unit.
