Our system is achieved by integrating diffractiondeep learning methods, which allows high-throughput lensless imaging system to display wide rangehigh-resolution images. In addition, the developed extraction chipsprototype were verified to accurately detect the numberproportion of blood cells under low blood demand. Our system shows great potential in point-of-care blood cells monitoring for cancer patients that could reduce infection riskmortality rate, increase efficacy of chemotherapysupport precision medicine.

Surface-enhanced Raman spectroscopy (SERS) is a useful analytical technique for detecting extremely small amounts of molecules. Herein, we designed a paper-based quasi-three-dimensional SERS substrate (P-SERS) that can provide potential to improve Raman analyses for food safety, pesticide poisoning, precision medicine, drug abuse and DNA/RNA testing. The sensitive, low-cost, flexible and disposable SERS substrate could be easily fabricated by physical deposition of gold nanoparticles array onto a filter paper. In this case, we are able to create non-continuous Au islands on the fiber surfaces, where the gaps between AuNPs can dramatically generate the high electric field to enhance Raman signal of target molecules.

"We present here a portable device with isothermally mediated loop amplification (LAMP) for the diagnosis of infectious diseases. The main components included (1) roller conveyor, (2) hotplate,(3) temperaturemotion control panels. After mixing all the solutions by rollingsqueezing the sealed compartments, the LAMP strip was heated for 30 min for amplification. Finally, fluorescence results can be read with the naked eyeon a smartphone under the UV lamp. The 700g device is powered by a portable charger, making it easier to detect pathogens in resource-limited environments."
