Image of FIG. 1.
FIG. 1.

(a) The schematic diagram of the mobile micro-Raman microfluidics analyzer. (b) The photo of the microfluidics analyzer.

Image of FIG. 2.
FIG. 2.

The configuration of the optical module. The abbreviation of the diameter of the lens and the focal length is d and f in the figure, respectively. All the parts of the optical module except the objective lens and the chip are in horizontal plane. The objective lens and the chip are in vertical plane.

FIG. 3.

The control flow chart of the micro-Raman microfluidics analyzer.

FIG. 4.

(a) The photograph of a y-type microfluidic chip. The inset is the cross section of the chip. (b)–(d) The microscopic images of the chip at P1, P2, and P3 as shown in (a). These images were obtained through the CCD camera in the analyzer. (e) SERS spectra of ATP solution, Ag colloid and the mixture of them at P1, P2, and P3 as shown in (a), respectively. The broad peak of the Raman spectra at P1 and P2 at about 1400 cm is the background of the glass substrate. Laser power on the sample was about 60 mW, and the integration time was 1s.
