Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction

open access: yesAdvanced Materials, EarlyView.
The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.

Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

open access: yesAdvanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Modification of Metal Microelectrodes with Vertical Graphene Structure for Enhanced Electrochemical Detection of Dopamine

open access: yesAdvanced Materials Interfaces, EarlyView.
In this article, vertical graphene‐modified microelectrodes (VGMEs) are fabricated by modifying vertical graphene on different types of metal microelectrodes (Au, Ti, Ag, and W) for enhanced electrochemical detection of DA. Moreover, the sensing performance on dopamine concentrations is explored with different electrochemical methods, including EIS, CV,
