Machine Learning‐Assisted Polarity‐Switchable Photoelectrochemical Platform Based on B‐Eu 2 O 3 Nanospindle and Dual‐Amplified Rod‐Shaped DNA Walker
This work first reports the synthesis of boron‐doped europium oxide (B‐Eu 2 O 3 ) nanospindle by carbonization of B‐doped Eu‐based metal organic framework (Eu‐MOF), as a high‐performance polarity‐switchable material with efficient charge transport. Based on B‐Eu 2 O 3 nanospindle and target‐triggered dual r...
