Enzymatic sensors have inherent problems such as the low stability and limited pH range in industrial and biomedical applications and therefore,more efficient nonenzymatic sensors are highly desirable.Herein,plasmafunctionalized defective MoSe_(2)is prepared and studied as a highly efficient catalyst for electrochemical sensing of H_(2)O_(2).Experiments and theoretical computations show that the plasma-induced Se multi-vacancies and nitrogen dopants generate new active sites,expose more edge active surfaces,narrow the bandgap,and strengthen binding with the·OH intermediate,which imparts new fundamental knowledge about the roles of defects in catalysis.The defective MoSe_(2)-catalyzed sensor delivers competitive performance in hydrogen peroxide detection such as a low detection limit of 12.6 nmol/L,wide operational pH range of 1−13,good long-term stability,and high selectivity.The portable sensor produced by screen printing confirms the excellent commercial potential and in addition,the results not only reveal a novel concept to design and fabricate high-performance sensors for H_(2)_(O2)but also provide insights into the effectiveness of surface modification of diverse catalytic materials.

Social media has changed the way we learn,educate,and interact with our peers.The dynamic nature of social media and their immediate availability through our portable devices(smartphones,tablets,smartwatches,etc.)is quickly transforming the way we participate in society.The scope of these digital tools is broad as they deal with many different aspects:Teaching and learning,case discussion,congresses coverage,peer to peer interaction,research are examples worth mentioning.The scientific societies considered more innovative,are promoting these tools between their members.These new concepts need to be known by the cardiologists to stay updated,as countless information is moving rapidly through these channels.We summarize the main reasons why learning how to use these tools to be part of the conversation is essential for the cardiologist in training or fully stablished.
