Zero‐shot temporal event localisation: Label‐free, training‐free, domain‐free
IET Computer Vision, 2023 Temporal event localisation (TEL) has recently attracted increasing attention due to the rapid development of video platforms. Existing methods are based on either fully/weakly supervised or unsupervised learning, and thus they rely on expensive data ...

Label-Free Concept Bottleneck Models
CoRR, 2023 Concept bottleneck models (CBM) are a popular way of creating more interpretable neural networks by having hidden layer neurons correspond to human-understandable concepts. However, existing CBMs and their variants have two crucial limitations: first, they need to collect labeled data for each of the predefined concepts, which is time consuming and ...

Label-free photoacoustic nanoscopy [PDF]
Journal of Biomedical Optics, 2014 Super-resolution microscopy techniques - capable of overcoming the diffraction limit of light - have opened new opportunities to explore subcellular structures and dynamics not resolvable in conventional far-field microscopy. However, relying on staining with exogenous fluorescent markers, these techniques can sometimes introduce undesired artifacts to

Wearable Label‐Free Optical Biodetectors: Progress and Perspectives
Advanced Photonics Research, 2021 Biomarkers are the primary indicators of human health. Measurements traditionally rely on targeted binding and assays, which, in turn, rely on specific “labels” that define the biomarker or molecule of interest.

Biopatterning for label-free detection [PDF]
Colloids and Surfaces B: Biointerfaces, 2010 We present a biopatterning technique suitable for applications which demand a high degree of surface cleanliness, such as immobilization of biological recognition elements onto label-free biosensors. In the case of label-free biosensing, the mechanism of signal transduction is based on surface bound matter, making them highly sensitive to surface ...

Label‐free discrimination of extracellular vesicles from large lipoproteins
Journal of Extracellular Vesicles, 2023 Extracellular vesicles (EVs) are increasingly gaining interest as biomarkers and therapeutics. Accurate sizing and quantification of EVs remain problematic, given their nanometre size range and small scattering cross‐sections.

Label-Free Monitoring of Diffusion in Microfluidics [PDF]
Micromachines, 2017 Label-free, real-time detection of concentration gradients is demonstrated in a microfluidic H-filter, using an integrated photonic crystal slab sensor to monitor sample refractive index with spatial resolution. The recorded diffusion profiles reveal root-mean-square diffusion lengths for non-fluorescing and non-absorbing molecules, both small (glucose,
