Flexible energy storage device is one of the most critical components as power source for wearable electronics. The emergence of MXenes, a growing family of 2D nanomaterials, has demonstrated a brand‐new possibility for flexible energy storage. However, the fabrication of MXene films with satisfactory mechanical, electrical, and electrochemical reliabilities remains challenging due to the weak interlayer...
Achieving fast transmembrane transmission of molecules in organisms is a challenging problem. Inspired by the transport of Dopmine (DA) in organisms, the DA transporter (DAT) binds to DA in a way that has a ring recognition (the recognition group is the tryptophan group). Herein, D‐Tryptophan‐pillar[5]arene (D‐Trp‐P5) functionalized conical nanochannel is constructed to achieve fast transmission of...
Metal aerogels represent an emerging type of functional porous materials with promising applications in diverse fields, but the fabrication of metal aerogels with specific structure and property still remains a challenge. Here, the authors report a new approach to fabricate metal aerogels by using ultrasmall metal nanoclusters (NCs) as functional building blocks. By taking D‐penicillamine‐stabilized...
Paper‐based assays for detection of physiologically important species are needed in medical theranostics owning to their superiorities in point of care testing, daily monitoring, and even visual readout by using chromogenic materials. In this work, a facile test strip is developed for visual detection of a neurotransmitter dopamine (DA) based on dual‐emission fluorescent molecularly imprinted polymer...
By simply coating the filter paper with dual‐emission fluorescent dopamine (DA)‐imprinted nanoparticles, DA test strips are easily obtained in article number 1803913 by Weidong Shi, Guoqing Pan, and co‐workers. The test strips enable direct, visual, and semiquantitative detection of DA in small amounts of biofluid samples with a rapid readout and low detection limit.
One challenge for multimodal therapy is to develop appropriate multifunctional agents to meet the requirements of potential applications. Photodynamic therapy (PDT) is proven to be an effective way to treat cancers. Diverse polycations, such as ethylenediamine‐functionalized poly(glycidyl methacrylate) (PGED) with plentiful primary amines, secondary amines, and hydroxyl groups, demonstrate good gene...
In article number 1700623, by Xiaowei Zeng, Lin Mei, and co‐workers, a pH‐sensitive drug delivery vehicle based on TPGS‐modified polydopamine‐coated mesoporous silica nanoparticles is developed. This nanoparticle shows good performance inhibiting cancer multidrug resistance by suppressing the function of the P‐glycoprotein. This drug‐loaded delivery platform exhibits significantly superior antitumor...
A nanocarrier system of d‐a‐tocopheryl polyethylene glycol 1000 succinate (TPGS)‐functionalized polydopamine‐coated mesoporous silica nanoparticles (NPs) is developed for sustainable and pH‐responsive delivery of doxorubicin (DOX) as a model drug for the treatment of drug‐resistant nonsmall cell lung cancer. Such nanoparticles are of desired particle size, drug loading, and drug release profile. The...
