Localized surface plasmon resonance (LSPR) is a longstudied nanoscale phenomenon of
considerable recent interest. 1, 2 These resonances, associated with noble metal …

This perspective gives an overview of recent developments in surface-enhanced Raman
scattering (SERS) for biosensing. We focus this review on SERS papers published in the last …

In vitro biosensors have been an integral component for early diagnosis of cancer in the
clinic. Among them, no-wash biosensors, which only depend on the simple mixing of the …

Plasmonics is an emerging field that examines the interaction between light and metallic
nanostructures at the metal-dielectric interface. Surface-enhanced Raman scattering (SERS) …

A rapid detection test for SARS-CoV-2 is urgently required to monitor virus spread and
containment. Here, we describe a test that uses nanoprobes, which are gold nanoparticles …

Aptamers are single-stranded DNA or RNA oligomers, identified from a random sequence
pool, with the ability to form unique and versatile tertiary structures that bind to cognate …

Chiral assemblies of nanoparticles (NPs) are typically constructed with helical or tetrahedral
geometries. Simple pairs of NPs are not expected to display chirality due to basic symmetry …

It has been almost 30 years since the invention of Systematic Evolution of Ligands by
Exponential Enrichment (SELEX) methodology and the description of the first aptamers. In …

A Au particle-on-wire system that can be used as a specific, sensitive, and multiplex DNA
sensor is developed. A pattern formed by multiple Au nanowire sensors provides positional …

Dopamine (DA) is a neurotransmitter which plays a key role in the life science. Self-
assembled Au@ Ag nanorod dimers based on aptamers were developed for ultrasensitive …
