Designing surface-enhanced Raman scattering (SERS) platforms beyond hotspot engineering: emerging opportunities in analyte manipulations and hybrid materials.
TLDR
Five major approaches to enhance SERS performance are outlined and can be integrated with engineered hotspots as a multifaceted strategy to further boost SERS sensitivities that are unachievable using hotspot engineering alone. Expand
SERS- and Electrochemically Active 3D Plasmonic Liquid Marbles for Molecular-Level Spectroelectrochemical Investigation of Microliter Reactions.
TLDR
The 3D configuration of the PLM-based EC-SERS system exhibits 2-fold and 10-fold superior electrochemical and SERS performance than conventional 2D platforms, which are pertinent in charge transfer processes. Expand
Two-Photon-Assisted Polymerization and Reduction: Emerging Formulations and Applications.
TLDR
This review critically discusses the importance of photoresist formulation in two-photon lithography, and evaluates the commercial photoresists to design micro-/nanostructures for promising applications in anti-counterfeiting, superomniphobicity, and micro-machines with movable parts. Expand
Plasmonic Colloidosomes as Three-Dimensional SERS Platforms with Enhanced Surface Area for Multiphase Sub-Microliter Toxin Sensing.
TLDR
This work introduces plasmonic colloidosome constructed from Ag nanocubes as an emulsion-based 3D SERS platform and demonstrates the first high-throughput multiplex molecular sensing across multiple liquid phases. Expand
Online Flowing Colloidosomes for Sequential Multi-analyte High-Throughput SERS Analysis.
TLDR
High-throughput multi-assay analysis is performed, which highlights that the system is capable of rapid identification and quantification of a sequence of samples containing various analytes and concentrations, and demonstrates high-resolution multiplex detection with fully preserved signal and Raman features of individual analytes in a mixture.

Concentrating Immiscible Molecules at Solid@MOF Interfacial Nanocavities to Drive an Inert Gas-Liquid Reaction at Ambient Conditions.
TLDR
An inert gas-liquid reaction between aniline and CO2 is driven by selectively concentrating these immiscible reactants at the interface between metal-organic framework and solid nanoparticles (solid@MOF), giving a more than 28-fold improvement to reaction efficiency as compared to ZIF-only and solid-only platforms.
