| 1 | Touchable cell biophysics property recognition platforms enable multifunctional blood smart health care显示文摘As a crucial biophysical property,red blood cell(RBC)deformability is pathologically altered in numerous disease states,and biochemical and structural changes occur over time in stored samples of otherwise normal RBCs.However,there is still a gap in applying it further to point-of-care blood devices due to the large external equipment(high-resolution microscope and microfluidic pump),associated operational difficulties,and professional analysis.Herein,we revolutionarily propose a smart optofluidic system to provide a differential diagnosis for blood testing via precise cell biophysics property recognition both mechanically and morphologically.Deformation of the RBC population is caused by pressing the hydrogel via an integrated mechanical transfer device.The biophysical properties of the cell population are obtained by the designed smartphone algorithm.Artificial intelligence-based modeling of cell biophysics properties related to blood diseases and quality was developed for online testing.We currently achieve 100%diagnostic accuracy for five typical clinical blood diseases(90 megaloblastic anemia,78 myelofibrosis,84 iron deficiency anemia,48 thrombotic thrombocytopenic purpura,and 48 thalassemias)via real-world prospective implementation;furthermore,personalized blood quality(for transfusion in cardiac surgery)monitoring is achieved with an accuracy of 96.9%.This work suggests a potential basis for next-generation blood smart health care devices. | Longfei Chen Yantong Liu Hongshan Xu Linlu Ma Yifan Wang Le Yu Fang Wang Jiaomeng Zhu Xuejia Hu Kezhen Yi Yi Yang Hui Shen Fuling Zhou Xiaoqi Gao Yanxiang Cheng Long Bai Yongwei Duan Fubing Wang Yimin Zhu | 2021 | Microsystems & Nanoengineering2021，7，6： | 0 |
