Surface‐enhanced Raman spectroscopy (SERS)‐based biosensors have attracted much attention for their label‐free detection, ultrahigh sensitivity, and unique molecular fingerprinting. In this study, a wafer‐scale, ultrasensitive, highly uniform, paper‐based, portable SERS detection platform featuring abundant and dense gold nanopearls with narrow gap distances, are prepared and deposited directly onto...

In article number 2207404, Chihchen Chen, Tzung‐Hai Yen, Dehui Wan, and co‐workers develop a paper‐based, portable surface‐enhanced Raman spectroscopy (SERS) detection platform with an extremely high Raman enhancement factor and detectability at sub‐femtomolar concentrations, even when operated with a portable NIR Raman spectrometer. The fabrication process involves depositing abundant...
In the context of thin‐film nanocomposite membranes with interlayer (TFNi), nanoparticles are deposited uniformly onto the support prior to the formation of the polyamide (PA) layer. The successful implementation of this approach relies on the ability of nanoparticles to meet strict requirements regarding their sizes, dispersibility, and compatibility. Nevertheless, the synthesis of covalent organic...
Both the uncoordinated Pb2+ and excess PbI2 in perovskite film will create defects and perturb carrier collection, thus leading to the open‐circuit voltage (VOC) loss and inducing rapid performance degradation of perovskite solar cells (PSCs). Herein, an additive of 3‐aminothiophene‐2‐carboxamide (3‐AzTca) that contains amide and amino and features a large molecular size is introduced to improve the...
Developing efficient heterojunction electrocatalysts and uncovering their atomic‐level interfacial mechanism in promoting sulfur‐species adsorption‐electrocatalysis are interesting yet challenging in lithium‐sulfur batteries (LSBs). Here, multifunctional SnS2‐MXene Mott–Schottky heterojunctions with interfacial built‐in electric field (BIEF) are developed, as a model to decipher their BIEF effect...
The development of multifunctional and robust swimming microrobots working at the free air–liquid interface has encountered challenge as new manipulation strategies are needed to overcome the complicated interfacial restrictions. Here, flexible but reliable mechanisms are shown that achieve a remote‐control bubble microrobot with multiple working modes and high maneuverability by the assistance of...
The design of nanomedicine for cancer therapy, especially the treatment of tumor metastasis has received great attention. Proteasome inhibition is accepted as a new strategy for cancer therapy. Despite being a big breakthrough in multiple myeloma therapy, carfilzomib (CFZ), a second‐in‐class proteasome inhibitor is still unsatisfactory for solid tumor and metastasis therapy. In this study, hollow...
Tumor cells adapt to excessive oxidative stress by actuating reactive oxygen species (ROS)‐defensing system, leading to a resistance to oxidation therapy. In this work, self‐delivery photodynamic synergists (designated as PhotoSyn) are developed for oxidative damage amplified tumor therapy. Specifically, PhotoSyn are fabricated by the self‐assembly of chlorine e6 (Ce6) and TH588 through π–π stacking...
Hierarchical emulsions are interesting for both scientific researches and practical applications. Hierarchical emulsions prepared by microfluidics require complicated device geometry and delicate control of flow rates. Here, a versatile method is developed to design hierarchical emulsions using microfluidic 3D droplet printing in droplet. The process of droplet printing in droplet mimics the dragonfly...
Quasi‐2D perovskites are enchanting alternative materials for solar cells due to their intrinsic stability. The manipulation of crystal orientation of quasi‐2D perovskites is indispensable to target efficient devices, however, the origin of orientation during the film fabrication process still lacks in‐depth understanding and convincing evidence yet, which hinders further boosting the performance...
Conjugated polymers are promising light harvesters for water reduction/oxidation due to their simple synthesis and adjustable bandgap. Herein, both cyanamide and triazole functional groups are first incorporated into a heptazine‐based carbon nitride (CN) polymer, resulting in a mesoporous conjugated cyanamide‐triazole‐heptazine polymer (CTHP) with different compositions by increasing the quantity...
A robust and transparent silica‐like coating that imparts superhydrophobicity to a surface through its hierarchical multilevel self‐assembled structure is demonstrated. This approach involves iterative steps of spin‐coating, annealing, and etching of polystyrene‐block‐polydimethylsiloxane block copolymer thin films to form a tailored multilayer nanoscale topographic pattern with a water contact angle...
Flexible planar micro‐supercapacitors (MSCs) with unique loose and porous nanofiber‐like electrode structures are fabricated by combining electrochemical deposition with inkjet printing. Benefiting from the resulting porous nanofiber‐like structures, the areal capacitance of the inkjet‐printed flexible planar MSCs is obviously enhanced to 46.6 mF cm−2, which is among the highest values ever reported...
