“…The oxidation of 3,3',5,5'tetramethylbenzidine (TMB) resulting in a colored product is a well-known phenomenon with TMB which is exploited in colorimetric sensors along with a wide variety of other nano-based materials. 554,555 Salts such as silver chloride (AgCl), sodium chloride (NaCl), iron chloride (FeCl3) and basic compounds such as triethylamine and potassium hydroxide (KOH) and the strong acid hydrochloric acid (HCl), are the other emerging small molecules more so in journal publications. Silver chloride (AgCl) is often used in reference electrodes [556][557][558] and as components of nanocomposites.…”

Since their inception in the early 1960s, the use of nanoscale materials has progressed in leaps and bounds, and their role in diverse fields ranging from human health to energy is undeniable. In this report, we utilize the CAS Content Collection, a vast repository of scientific information extracted from journal and patent publications, to identify emerging topics in this field. This involves understanding trends, such as the growth of certain topics over time, as well as establishing relationships between emerging topics. We achieved this by using a host of strategies including a quantitative natural language processing (NLP) approach to identify 279 emerging topics and sub-topics across three major categories – materials, applications, and properties – by surveying roughly 3 million publications in the nanoscience landscape. This wealth of information has been condensed into several conceptual mind maps and other graphs that provide metrics related to the growth of identified emerging concepts, group them into hierarchical classes, and explore the connections between them. We delved deeper into four major emerging applications of nanoscale materials – drug delivery, sensors, energy, and catalysis – to provide a more comprehensive and detailed picture of the use of nanotechnology in these fields. In addition, we leveraged the CAS registry, consisting of over 250 million substances, to determine and discover substances across varied classes (such as polymers, elements, organic/inorganic molecules) and how they are utilized in the 4 major applications. Our extensive analysis taking advantage of an NLP-based approach along with robust CAS indexing provides valuable insights in the field that we hope can help to inform and drive future research efforts.

The peroxidase (POD)‐mimic nanozymes can be a potential tool for point‐of‐care (POC) diseases diagnosis. However, the complex sample matrix and unspecific multiple‐enzyme activities of nanozyme can generate false background signal and decrease the diagnostic accuracy. Here, a magnetic and POD‐specific covalent organic framework (COF) confined osmium (Os) nanoclusterzyme Fe3O4@COF@Os is developed for biomarkers biosensing. First, found that the catalytic activity and specificity of Fe3O4@COF@Os can be regulated by the deoxidizers and the functional groups of COF ligands. By using ascorbic acid as deoxidizer and F functional COF ligands, Fe3O4@COF@Os displayed superior POD‐specific activity and negligible oxidase (OXD) and catalase (CAT) mimic activity. Therefore, Fe3O4@COF@Os can separate and analyze of targets in bio‐matrix without background interference. For application, Fe3O4@COF@Os based lateral flow assay is established for serum cancer biomarker prostate‐specific antigen, the detection limit is 3.83 pg mL−1. For clinical prostatic cancer samples, the accuracy is 100% with a correlation coefficient of 0.998 with commercial ELISA kit. For chronic disease biomarker sensing, salivary glucose can be quantified as low as 0.1 µm, with negligible background interference and favorable recyclability. This specific magnetic nanozymes can offer a promising pretreatment‐free and POC strategy for rapid and accurate diseases diagnosis.
