Fig. 3: DTMS monitoring and intervening myocardial infarction (MI).
From: Two way workable microchanneled hydrogel suture to diagnose, treat and monitor the infarcted heart
a Scheme illustration: Normal group: normal rats; MI group: no intervention after MI; SNAP group: single SNAP treatment after MI; DTMS group: DTMS treated MI; S-DTMS group: SNAP and DTMS treated MI b Surface ECG signals of rats in each group measured by electrophysiology workstation after 1 month. c, d ECG signals of rats in each group remotely measured by DTMS and Bluetooth module after 1 month. e Micro-CT imaging of DTMS which passed through the chest wall and myocardial tissue, finally exited the body. (i) Soft tissue image prior to iohexol perfusion. (ii) High-density images prior to iohexol perfusion. (iii) Soft tissue image after iohexol perfusion. (iv) High-density images after iohexol perfusion. f Fluorescence imaging of BSA-DIR via DTMS by micro-pump on demand for two times (100 μL/min). g Quantification of average radiation efficiency micro-pumped DTMS perfusion. N = 4 biologically independent replicates. All values are presented as mean ± SD.
