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 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

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.

The Clean Label Concept: Novel Approaches in Gluten-Free Breadmaking
Applied Sciences, 2021 The commonly used term of “clean label” refers to food products that do not contain additives (E numbers). Although there is not always a scientific reason for believing that additive-free products are healthier, clean label products are becoming more ...

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,

Label‐free characterization of an extracellular vesicle‐based therapeutic
Journal of Extracellular Vesicles, 2021 Interest in mesenchymal stem cell derived extracellular vesicles (MSC‐EVs) as therapeutic agents has dramatically increased over the last decade. Current approaches to the characterization and quality control of EV‐based therapeutics include particle ...
