Patent number: 11835442Abstract: A flow imaging system based on matrix laser scanning are provided. In the system, a beam splitter component modulates continuous laser generated by a laser source, and the continuous laser is focused on a focal plane by an illumination objective to form matrix spots. The matrix spots are irradiated on a single-cell axial flow of a fluid focusing component. When cells in the single-cell axial flow pass through the matrix spots, a fluorescent signal and a scattered light signal generated are received by a light collecting objective, and then sent to a photoelectric detector through a condenser. The photoelectric detector converts the fluorescence and scattered light signals excited into voltage signals, and the collecting card collects and converts the signals into digital signals, and sends the digital signals to a computer to be recovered through the computer, so as to obtain a cell image.Type: GrantFiled: September 14, 2021Date of Patent: December 5, 2023Assignee: TSINGHUA UNIVERSITYInventors: Zheng You, Yong Han, Jingjing Zhao

Patent number: 11808698Abstract: A device for the detection of analytes comprises a substrate (10) with nano-antennas (11,12). The nano-antennas (11,12) comprise an antenna material (11m, 12m) for forming resonant antenna structures which receive and resonantly interact with source light (L0) to form respective resonance peaks (R1,R2) over a resonant wavelength range (A1,A2) overlapping respective signature wavelength (?1,?2) of a target analyte (A). The resonant interaction causes a locally concentrated field (Ec) of the source light (L0) in the resonant wavelength range (?1,?2). The concentrated intensity (Ic) is localized around a respective target location (T1,T2) which is provided with a sorption material (11s, 12s) that sorbs the target analyte (A). This provides a locally increased analyte concentration (Ac) of the target analyte (A) coinciding with the locally concentrated field (Ec) of the source light (L0). Accordingly, the interaction of the source light (L0) with the target analyte (A) is enhanced.Type: GrantFiled: June 27, 2019Date of Patent: November 7, 2023Assignee: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk onderzoek TNOInventors: Beniamino Sciacca, Arjen Boersma
