An effective dual-mode microfluidic paper-based analysis device (μPAD) was proposed via Bi2S3@MoS2 nanoflowers combined with octahedral CeO2 for ultrasensitive miRNA-141 bioassay. To obtain the amplified electrochemical signal, Bi2S3@MoS2 nanoflowers were first in situ grown onto the surface of cellulose fibers to promote the reduction of H2O2. The prism-anchored octahedral CeO2 nanoparticles with a great catalytic function on the reduction of H2O2 were linked up to the functionalized cellulose fibers through
