Oxidative stress and local overactive inflammation have been considered major obstacles in diabetic wound treatment. Although antiphlogistic tactics have been reported widely, they are also challenged by pathogen contamination and compromised angiogenesis. Herein, a versatile integrated nanoagent based on 2D reductive covalent organic frameworks coated with antibacterial immuno‐engineered exosome...
For the first time, topological insulator bismuth selenide nanoparticles (Bi2Se3 NP) are core–shelled with gold (Au@Bi2Se3) i) to represent considerably small‐sized (11 nm) plasmonic nanoparticles, enabling accurate bioimaging in the near‐infrared region; ii) to substantially improve Bi2Se3 biocompatibility, iii) water dispersibility, and iv) surface functionalization capability through straightforward...
A newly developed electrochemical biosensor composed of a topological insulator (TI) and metallic DNA (mDNA) is fabricated. The bismuth selenide nanoparticle (Bi2Se3 NP) is synthesized and sandwiched between the gold electrode and another Au‐deposited thin layer (Bi2Se3@Au). Then, eight‐silver‐ion mediated double‐stranded DNA (mDNA) is immobilized onto the substrate (Bi2Se3@Au‐mDNA) for the further...
