Wearable electronics are attracting increasing interest due to the emerging Internet of Things (IoT). Compared to their inorganic counterparts, stretchable organic semiconductors (SOSs) are promising candidates for wearable electronics due to their excellent properties, including light weight, stretchability, dissolubility, compatibility with flexible substrates, easy tuning of electrical properties,...
The catalytic activity and selectivity of single‐atom sites catalysts is strongly dependent on the supports structure and central metal coordination environment. However, the further optimization of electronic configuration to improve the catalytic performance is usually hampered by the strong coordination effect between the support and metal atoms. Herein, it is discovered that enzyme‐mimicking catalytic...
In article number 1906644, Guoqing Pan and co‐workers comprehensively discuss the recent progress of molecularly imprinted synthetic antibodies (MISAs) from fundamental chemical design to their emerging biomedical applications. Meanwhile, the possibility of MISAs as qualified substitutes or even to transcend the performance of natural antibodies is discussed from the perspective of frontier needs...
Billions of dollars are invested into the monoclonal antibody market every year to meet the increasing demand in clinical diagnosis and therapy. However, natural antibodies still suffer from poor stability and high cost, as well as ethical issues in animal experiments. Thus, developing antibody substitutes or mimics is a long‐term goal for scientists. The molecular imprinting technique presents one...
Single‐atom catalysts (SACs) have attracted extensive attention in the catalysis field because of their remarkable catalytic activity, gratifying stability, excellent selectivity, and 100% atom utilization. With atomically dispersed metal active sites, Fe‐N‐C SACs can mimic oxidase by activating O2 into reactive oxygen species, O2−• radicals. Taking advantages of this property, single‐atom nanozymes...
Noble metal hydrogels/aerogels with macroscopic nanoassemblies characterized by ultralow density, profuse continuous porosity, and extremely large surface area have gained abundant interest due to not only their tunable physicochemical properties, but also promising applications in catalysis and sensing. Coupling the increased reaction temperature with dopamine‐induced effect, herein, a one‐step synthetic...
Herein, the design of a DNA‐based chiral biosensor is described utilizing the self‐assembly of shell core–gold (Au) satellite nanostructures for the detection of mycotoxin, ochratoxin A (OTA). The assembly of core–satellite nanostructures based on OTA‐aptamer binding exhibits a strong chiral signal with an intense circular dichroism (CD) peak. The integrity of the assembly of core–satellite nanostructures...
The instability of few‐layer black phosphorus (FL‐BP) hampers its further applications. Here, it can be demonstrated that the instability of FL‐BP can also be the advantage for application in biosensor. First, gold nanoparticle/FL‐BP (BP‐Au) hybrid is facilely synthesized by mixing Au precursor with FL‐BP. BP‐Au shows outstanding catalytic activity (K = 1120 s−1 g−1) and low activation energy (17...
