A flexible electromagnetic interference(EMI)shielding film was innovatively fabricated using both low melting temperature solder arrays and amorphous soft magnet particulates consolidated on a polyethylene terephthalate(PET)***,the IneSneBi solder arrays presented a low melting point of 99.4C,which enabled attachment to the heat-sensitive plastic substrate without any thermal damage,and a low electrical resistivity of 14.1 mU cm,making them very effective at interrupting EM ***,the solder arrays with a high thermal conductivity of 61.2 W/(m$K)at 298.15 K were also useful as a thermal conductor for a heat ***,the solder arrays provide efficient electrical and thermal channels for electron transport induced by abruptly or consistently created EM waves due to suddenly turning on and the long term operation of electronics,***,the Fe-based magnetic particulates were added and resulted in effective saturation magnetization of 161.1 emu/g,remanence of 2.9 emu/g,and coercivity of 12.5 G,thus were able to disturb the EM pathway because of their soft magnetic ***,the hybrid EMI shielding film with exceptionally high electrical and thermal conductivity and superior soft magnetic properties provided remarkable shielding effectiveness of 102.5 dB at 10.2 GHz.

Hepatocellular carcinoma(HCC)is the second most common cancer and the third leading cause of cancer-related death worldwide[1].Recently,HCC incidence and mortality rates have further increased due to changes in the global social environment and dietary habits[2].HCC is treated by surgical resection or combination chemotherapy,but the overall survival rate of HCC patients has not improved,and the recurrence rate is still high due to strong invasiveness and resistance to chemotherapy[3].
