Advances in surface-enhanced Raman scattering (SERS) detection have helped to
overcome the limitations of traditional in vitro diagnostic methods, such as fluorescence and …

Plasmonic nanocavities exhibit exceptional capabilities in visualizing the internal structure of
a single molecule at sub-nanometer resolution. Among these, an easily manufacturable …

Anti-Stokes photoluminescence (PL) is light emission at a higher photon energy than the
excitation, with applications in optical cooling, bioimaging, lasing, and quantum optics. Here …

Realizing the dual emission of fluorescence–phosphorescence in a single system is an
extremely important topic in the fields of biological imaging, sensing, and information …

Molecular chirality plays fundamental roles in biology. The chiral response of a molecule
occurs at a specific spectral position, determined by its molecular structure. This fingerprint …

We show using time-dependent density functional theory (TDDFT) that light can be confined
into slot waveguide modes residing between individual atomic layers of coinage metals …

Ultrafast laser processing technology has offered a wide range of opportunities in
micro/nano fabrication and other fields such as nanotechnology, biotechnology, energy …

Conjugated polymers are promising material candidates for many future applications in
flexible displays, organic circuits, and sensors. Their performance is strongly affected by …

Hot spots can generate intense local electromagnetic (EM) fields, thereby boosting diverse
innovative applications. However, these applications may face challenges due to their subtle …

Metal nanocrystals synthesized in achiral environments usually exhibit no chiroptical effects.
However, by placing nominally achiral nanocrystals 1.3 nm above gold films, we find giant …
