One Year of ACS Nanoscience Au

I is hard to believe that a year has passed already since the first issue of ACS Nanoscience Au was published in December of 2021. In the six issues in Volume 2, which constitute the first full year, ACS Nanoscience Au has published 44 contributions, including 3 Editorials, 1 Perspective, 11 Reviews, and 29 Articles/Letters. In total, all of the content published thus far in ACS Nanoscience Au has been viewed more than 88,000 times! This large number of views is a testament to the journal’s outstanding content, as well as its visibility and reach, which are maximized by its open access status. The published papers have been authored and accessed by researchers from around the world, highlighting the global impact and visibility of ACS Nanoscience Au. These papers also span the breadth of topics that define the field of nanoscience. To highlight the topical diversity and impact of the first year of ACS Nanoscience Au, the papers highlighted below are among the most accessed and cited so far. They represent a collection of Reviews and Perspectives in nanomedicine, nanoelectronics, active matter, environmental remediation, 1-D and 2-D materials, and energy, as well as Articles and Letters in nanoclusters, nanomedicine, nanoagriculture, nanowires, halide perovskites, SERS imaging, nanophotonics, DNA nanotechnology, and MXenes. Luciferase-Based Biosensors in the Era of the COVID-19 Pandemic (ACS Nanosci. Au 2021, 1, 15−37). Our very first published Review, by Taha Azad, Carolina Ilkow, John Bell, and co-workers, holds the current record for the highest number of article views in the journal. Viruses and proteins are inherently nanoscopic systems, and this Review highlights the development and use of biosensors to study virus biology, including SARS-CoV-2. Design of Over-1000 nm Near-Infrared Fluorescent Polymeric Micellar Nanoparticles by Matching the Solubility Parameter of the Core Polymer and Dye (ACS Nanosci. Au 2021, 1, 61−68). This Article by Masakazu Umezawa, Kohei Soga, and co-workers demonstrated a strategy for designing polymeric nanoparticles for biological imaging. They showed how near-infrared fluorescent probes could be accessed by matching the solubility parameters of a core polymer and a dye molecule. Gold Nanoparticle Smartphone Platform for Diagnosing Urinary Tract Infections (ACS Nanosci. Au 2022, 2, 324− 332). The diagnosis of urinary tract infections is important in medicine. In this Article, Warren Chan and co-workers used a gold nanoparticle colorimetric approach to detect clinically relevant bacteria concentrations, finding it both inexpensive and fast. They then used this to develop a smartphone platform for detecting urinary tract infections. Ligand Ratio Plays a Critical Role in the Design of Optimal Multifunctional Gold Nanoclusters for Targeted Gastric Cancer Therapy (ACS Nanosci. Au 2021, 1, 47−60). This Article by Mariá Francisca Matus, Sami Malola, and Hannu Hak̈kinen was the first to be accepted for publication in ACS Nanoscience Au. It shows how gold nanoclusters can be computationally designed to be functionalized with molecules that are relevant to gastric cancer therapy and how various aspects of the ligand shell, including ligand ratio, may impact properties. Topogami: Topologically Linked DNA Origami (ACS Nanosci. Au 2022, 2, 57−63). DNA nanotechnology uses DNA to make nanostructures, including 2-D and 3-D shapes, that can be used in many applications. In this Article, Jonathan Heddle and co-workers demonstrate a general method for designing and producing DNA origami with linked (catenated) DNA strands. Such topologically linked DNA origami structures were previously challenging to make. Development of a Preemergent Nanoherbicide: From Efficiency Evaluation to the Assessment of Environmental Fate and Risks to Soil Microorganisms (ACS Nanosci. Au 2022, 2, 307−323). The development of nanotechnology solutions for agriculture applications is expanding. In this Article, Vanessa Takeshita, Leonardo Fernandes Fraceto, and co-workers studied the stability and properties of a herbicide encapsulated in polymeric nanoparticles. The authors concluded that this nanoherbicide system offered increased weed control with low environmental risk. Micromachines for Microplastics Treatment (ACS Nanosci. Au 2022, 2, 225−232). Active matter is a rapidly growing field, including both fundamental development/understanding and applications. This Review, by Soňa Hermanova ́ and Martin Pumera, highlights one of these applications−the use of selfpropelled micromachines (with nanoscopic components and features) for an important aspect of modern environmental remediation. Metal-Oxide Nanomaterials Synthesis and Applications in Flexible and Wearable Sensors (ACS Nanosci. Au 2022, 2, 64−92). This Review by Daeho Lee, Seung Swan Ko, and coworkers has been gaining excellent traction in the community. Here, the authors review key factors for improving metal oxide
