In one aspect, disclosed herein are devices, systems, and methods for assessing human health states based on non-shadow imaging of sclera, or whites, of one or both eyes. In one aspect, the device is an on-body device. In one aspect, the system comprises a positioning aperture, an illuminating apparatus, an imaging apparatus, and/or a processing apparatus. In one aspect, the process only takes a short period of time to take images of the sclera without any operation of splicing multiple images. In one aspect, the device or system improves the quality of images by avoiding the formation of reflection of the illuminating apparatus on the images of the sclera. In a further aspect, the system can utilize the sclera images to obtain information of eye diseases and to predict the physiological and pathological changes in the health status of subject or diagnostic results, which can provide helpful information for medical diagnosis.

A multi-index detection microfluidic chip is provided. A bottom plate (1) and a cover plate (2) that matches the bottom plate (1) and seals it are provided in the microfluidic chip. The center of the microfluidic chip has a through-hole (3). The bottom plate (1) has one or more wave-shaped main channel (s ) (4), one end of each of the main channel (4) connected to a sample injection hole (9) on the bottom plate (1), and the other end connected to an exhaust hole (10) on the bottom plate (1). The valley on the main channel (1) is distal to the through-hole (3), and the peak is proximal to the through-hole (3). Each valley of the main channel (1) is connected to a reaction chamber (6) by a linking channel (5). The linking channel (5) comprises one or more buffering chambers (7). The microfluidic chip can be used in detection by fluorescence, turbidity, color, detection equipment, and/or direct observation by the naked eyes. The detection is real-time as the reaction occurs or after the reaction.

The present disclosure in some embodiments provides a flow cell sorting system, a focus detection method, as well as a fluidic chip. In one aspect, the fluidic chip comprises a cover sheet and one or more substrate layers, and one or more channels in each of the fluidic chips. In one aspect, the cells or other analytes in a sample are focused onto the same plane as they flow through the fluidic channel. In another aspect, the cells or other analytes on the same plane are irradiated with the same light intensity, for example, by a flat-top laser beam. This combination eliminates or reduces variation caused by cells at different positions receiving different intensities of the excitation light, and therefore improves accuracy of the flow cytometry analysis. In another aspect, a sorting apparatus is designed at the junction of the detection area and the outlet channel to separate the target cells.
