Practical applications of synthetic self‐propelled nano and microparticles for microrobotics, targeted drug delivery, and manipulation at the nanoscale are rapidly expanding. However, fabrication limitations often hinder progress, resulting in relatively simple shapes and limited functionality. Here, taking advantage of 3D nanoscale printing, chiral micropropellers powered by the hydrogen peroxide...
Carbonized Polymer Dots
In article number 2106863, Yeqing Chen, Ping Liang, Jun Lin, and co‐workers synthesize transition metal Mn ions doped in the form of covalent Mn–O bonds. The Mn–O bridge accelerates the electron flow between adjacent sp2 domains and enhances the electron transport in the Mn–carbonized polymer dots, thus improving the photoluminescence quantum yield and catalytic performance...
Carbonized polymer dots (CPDs) have received tremendous attention during the last decade due to their excellent fluorescent properties and catalytic performance. Doping CPDs with transition metal atoms accelerates the local electron flow in CPDs and improves the fluorescent properties and catalytic performance of the CPDs. However, the binding sites and the formation mechanisms of the transition‐metal‐atom‐doped...
Gold nanoparticles (AuNPs) pose a great challenge in the development of nanotracers that can self‐adaptively alter their properties in response to certain cellular environments for long‐term stem cell tracking. Herein, pH‐sensitive Au nanotracers (CPP‐PSD@Au) are fabricated by sequential coupling of AuNPs with sulfonamide‐based polymer (PSD) and cell‐penetrating peptide (CPP), which can be efficiently...
Human mesenchymal stem cells (hMSCs), due to their immune regulation and collateral secretion effects, are currently explored for potential therapy of idiopathic pulmonary fibrosis (IPF). Understanding the migration, homing, functions, and survival of transplanted hMSCs in vivo is critical to successful IPF treatment. Therefore, it is highly desired to develop noninvasive and effective imaging technologies...
Cancer‐targeted nanotechnology is experiencing the trend of finding new materials with multiple functions for imaging and therapeutic applications. With the rapid development of the related fields, there exists a large number of reports regarding theranostic nanomedicine, decreasing the gap between cancer diagnosis and treatment with minimized separate comprehensions. In order to present an overview...
