Zero‐shot temporal event localisation: Label‐free, training‐free, domain‐free

open access: yesIET 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 photoacoustic nanoscopy [PDF]

open access: yesJournal 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

open access: yesAdvanced 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.

Geometric structure design of passive label-free microfluidic systems for biological micro-object separation

open access: yesMicrosystems & Nanoengineering, 2022
Passive and label-free microfluidic devices have no complex external accessories or detection-interfering label particles. These devices are now widely used in medical and bioresearch applications, including cell focusing and cell separation.

Label‐free discrimination of extracellular vesicles from large lipoproteins

open access: yesJournal 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

open access: yesApplied 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 characterization of an extracellular vesicle‐based therapeutic

open access: yesJournal 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 ...

Label-free receptor assays [PDF]

open access: yesDrug Discovery Today: Technologies, 2010
Label-free biosensors offer integrated, kinetic and multi-parametric measures of receptor biology and ligand pharmacology in whole cells. Being highly sensitive and pathway-unbiased, label-free receptor assays can be used to probe the systems cell biology including pleiotropic signaling of receptors, and to characterize the functional selectivity and ...

Metamaterial-based label-free optical biosensing

open access: yesCailiao gongcheng, 2021
Metamaterials have drawn extensive attention for their fine regulation of electromagnetic waves at subwavelength scales. They have abundant electromagnetic modes, and support highly confined and enhanced electromagnetic fields on the surface which are ...
