An Efficient Heat and Peroxynitrite Generating Nanoplatform for Multimodal Imaging‐guided Precision Tumor Phototherapy

Aggregate, EarlyView.
Reported herein is the rational‐designed aggregation‐induced emission molecule (BPT), its nanoparticles (BPT NPs), and further processed heat and peroxynitrite generating nanoplatform for precision multimodal imaging‐guided tumor phototherapy. This nanoplatform showed near‐infrared II fluorescence, photothermal, and photoacoustic imaging capabilities ...

Multifunctional Ultra‐Bright Plasmonic Gold@Fluorescence Nanoprobe for Biomedical Applications

Aggregate, EarlyView.
Plasmonic gold nanoparticles (AuNPs) with intrinsic superiorities in metal‐enhanced fluorescence (MEF) have been widely utilized in amplifying signal enhancement, fluorescent labeling, and theranostics. This review systematically discusses plasmonic AuNPs‐driven MEFs, from their enhancement mechanisms, influencing factors, and enhanced types, to their ...

Generative Inverse Design of Metamaterials with Functional Responses by Interpretable Learning

Advanced Intelligent Systems, EarlyView.
This work introduces random‐forest‐based interpretable generative inverse design (RIGID), a new single‐shot inverse design method for metamaterials using interpretable machine learning and Markov chain Monte Carlo sampling. Once trained on a small dataset, RIGID can estimate the likelihood of designs achieving target behaviors (e.g., wave‐based ...

Accessible ecophysiological tools for seabird conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1983-2002, December 2022., 2022
Abstract Seabirds are the most endangered avian taxa on Earth, with over a third of species globally threatened. To help slow their decline, conservation physiology seeks to determine how seabird responses to climatic and anthropogenic threats influence demographic processes, but it is not widely utilized in monitoring.
