Single-molecule fluorescence currently requires specialized imaging equipment due to the low signal of a single emitter. Here the authors introduce NanoAntennas with Cleared HOtSpots (NACHOS) to boost the signal sufficient for detection of a single e

Fluorescent nanoparticles (NPs) help to increase spatial and temporal resolution in bioimaging. Advanced microscopy techniques require very bright NPs that exhibit either stable emission for single-particle tracking or complete on/off switching (blin

Here, we explore the enhancement of single-molecule emission by a polymeric nanoantenna that can harvest energy from thousands of donor dyes to a single acceptor. In this nanoantenna, the cationic dyes are brought together, in very close proximity, u

Uncontrolled release of encapsulated drugs and contrast agents from biodegradable polymer nanoparticles (NPs) is a central problem in drug delivery and bioimaging. In particular, it concerns polymeric NPs prepared by nanoprecipitation, where this rel

Methods and Applications in Fluorescence
Fluorescent dyes used for single-molecule spectroscopy can undergo millions of excitation-emission cycles before photobleaching. Due to the upconcentration of light in a plasmonic hotspot, the conditions for fluorescent dyes are even more demanding i

Because of the limited signal-to-background ratio, molecular diagnostics requires molecular amplification of the target molecules or molecular signal amplification after target recognition. For direct molecular detection, we demonstrate a purely phys
