Framework for Developing a Simple Method of Analyzing Environmental Bacterial Cells: Combining Single-Round DNA Aptamer Selection with Gold Nanoparticle Sensor Development for Legionella pneumophila Detection

Koji Matsunaga, Yuiko Tasaki‐Handa, Yota Suzuki, Taihei Murakami et autres

Abstract Monitoring pathogenic microorganisms in public and environmental waters is important for protecting ecosystems and human health; however, current detection methods are expensive, labor-intensive, and time-consuming. Although DNA aptasensors can potentially overcome these limitations, conventional aptamer selections often fail to secure high-affinity …

Pore size as a primary factor governing colloidal fouling control by MF/UF pretreatment in seawater reverse osmosis desalination

Hiroshi Yamamura, Yoshimasa Watanabe, Hisashi Satoh

ABSTRACT Membrane fouling remains a major bottleneck for seawater reverse osmosis (SWRO) desalination, and microfiltration/ultrafiltration (MF/UF) pretreatment is increasingly adopted to mitigate it. However, the relative importance of membrane material versus pore size has not been clarified through systematic comparison. Here we …
