"Metal-organic framework-based nanoarchitectonics: A promising material" by Peisen Huang, Wenjie Wu et al.

Over recent decades, the widespread use of pesticides has been instrumental in securing a global food supply. However, this has led to significant environmental pollution concerns. Given the prevalent use of organophosphorus pesticides (OPs), there is an urgent need to develop sensors that can detect OPs with high selectivity and sensitivity. Electrochemical sensors offer an affordable and highly efficient solution for this challenge. Particularly, there have been remarkable advancements in creating metal–organic framework (MOF)-based electrochemical sensors. This review delves into the current advancements of MOF-based electrochemical sensors, emphasizing their use in detecting OPs. We investigate prevalent MOF modifications, detail methods for affixing MOF materials to various electrodes, and compare the electrochemical performance and stability of these methods. We also provide insights into the design principles of MOFs used in the electrochemical detection of OPs, breaking down ....

"Peptide-nanoparticle conjugates as a theranostic platform" by Suhyeon Kim, Young Hyun No et al.

Theranostic platforms have emerged as advanced systems integrating diagnostic and therapeutic agents to enable personalized medicine tailored to the specific characteristics of each patient's disease. However, conventional theranostic strategies face challenges in achieving high specificity and sensitivity for diagnosis and therapy. This necessitates the development of novel platforms to improve diagnostic accuracy and therapeutic efficacy. Peptide-nanoparticle conjugates (PNCs) have recently gained attention as promising cancer theranostic platforms, offering enhanced specificity and accuracy. PNCs combine the favorable features of nanoparticles with the bioactivity, biocompatibility, and multifunctionality of peptides, overcoming individual material limitations and synergistically controlling relevant biological activities. In this review, we explore the potential of PNCs as highly effective and accurate theranostic platforms, focusing on cancer theranostics. We provide backgrou ....

"Synthesis Strategies and Nanoarchitectonics for High-Performance Trans" by Seungho Baek, Suhyeon Kim et al.

Transition metal dichalcogenides (TMDC) exhibit highly superior electrical properties and are typically obtained through mechanical exfoliation. This method has significant limitations, however, such as patterning issues and non-uniformity, which hinder their application in integrated circuits as transistors and array pixel displays. To overcome these challenges, various large-scale deposition methods have been developed. In this review, we introduce five major methods for TMDC deposition: chemical vapor deposition, physical vapor deposition, atomic layer deposition, pulsed laser deposition, and ink-jet printing. An overview of each method is provided in the following order: surface analysis, electrical characteristics, and limitations of each method are discussed. Furthermore, we present three key strategies for an advanced device fabrication using the discussed deposition methods. By implementing these strategies, we can accelerate the development of highly crystalline and scalable T ....

"Nanoarchitectonics of the cathode to improve the reversibility of Li–O" by Hien Thi Thu Pham, Jonghyeok Yun et al.

The strategic design of the cathode is a critical feature for high-performance and long-lasting reversibility of an energy storage system. In particular, the round-trip efficiency and cycling performance of nonaqueous lithium–oxygen batteries are governed by minimizing the discharge products, such as Li2O and Li2O2. Recently, a metal–organic framework has been directly pyrolyzed into a carbon frame with controllable pore volume and size. Furthermore, selective metallic catalysts can also be obtained by adjusting metal ions for outstanding electrochemical reactions. In this study, various bimetallic zeolitic imidazolate framework (ZIF)-derived carbons were designed by varying the ratio of Zn to Co ions. Moreover, carbon nanotubes (CNTs) are added to improve the electrical conductivity further, ultimately leading to better electrochemical stability in the cathode. As a result, the optimized bimetallic ZIF–carbon/CNT composite exhibits a high discharge capacity of 16,000 mAh·g−1, ....
