The invention provides an
ultraviolet biological
chip integrated sensor, and relates to the field of design and manufacturing of
biological warfare agent sensors. In the field, all light sources of the conventional LIF detection systems generate
ultraviolet light by frequency multiplication of impulsive visible or
infrared light; the conventional LIF detection
system has the defects of high price, low efficiency, large volume and crispness, and is inconvenient for real-time detection and outdoor use; and the impulsive
ultraviolet light is low in duty ratio, and has low detection sensitivity to biological
suspended particles, and the
light intensity of the conventional continuous
ultraviolet light is not high enough to excite the biological
suspended particles to fluoresce; and all these problems are great obstacles in the application of the detection
system. The ultraviolet biological
chip integrated sensor of the invention uses multi-
wavelength ultraviolet LEDs as excitation light sources and overcomes the defects of the conventional
light source; the multi-
wavelength ultraviolet LEDs, an Si-PIN
detector and an ultraviolet filter plate are integrated on the same substrate, so that the sensor has the capability of detecting and identifying various
biological warfare agents and can meet the light, firm, quick-response and high-sensitivity use requirements of the field environmental on the
detector while improving the detection efficiency and lowering a detection
false alarm rate.
