Label-free biosensors are devices that use biological or chemical receptors to detect analytes (molecules) in a sample. They give detailed information on the selectivity, affinity, and, in many cases, also the binding kinetics and thermodynamics of an interaction. Although they can be powerful tools in the hands of a skilled user, there is often a lack

In this chapter, we focus on label-free biosensors. First, we look at sensors with optical detection. In this context, the Mach–Zehnder interferometer and the surface plasmon resonance offer the possibility to limit the optical examination to shallow surface layers. The second group are the gravimetric biosensors.

Label-Free Sensing on Microarrays
2016Microarrays of biological molecules such as DNAs, proteins, carbohydrates, and small molecules provide a high-throughput platform for screening tens of thousands of biomolecular interactions simultaneously, facilitating the functional characterization of these biomolecules in areas of genomics, proteomics, glycomics, and cytomics.

Label-free biodetection using a smartphone
Lab on a Chip, 2013Utilizing its integrated camera as a spectrometer, we demonstrate the use of a smartphone as the detection instrument for a label-free photonic crystal biosensor. A custom-designed cradle holds the smartphone in fixed alignment with optical components, allowing for accurate and repeatable measurements of shifts in the resonant wavelength of the sensor.

Label-free capacitance DNA sensing
2013 Seventh International Conference on Sensing Technology (ICST), 2013This paper presents the use of direct capacitance measurements for label free hybridization detection of ssDNA immobilized directly on a gold interdigitated array of microelectrodes (IDAM). Thiol modified 18 bases long Poly-dT ssDNA molecules were immobilized on the Au IDAM surface without the use of any isolative self assembled monolayer (SAM ...

Virtual Staining of Label-free Tissue
Frontiers in Optics + Laser Science 2024 (FiO, LS)We will cover deep learning-based virtual staining techniques that can generate different types of histological stains from label-free microscopic images of unstained samples by using, e.g., autofluorescence microscopy, quantitative phase imaging and reflectance confocal microscopy.

Label-Free Quantitative Phosphoproteomics for Algae
2020The unicellular alga Chlamydomonas reinhardtii is a model photosynthetic organism for the study of microalgal processes. Along with genomic and transcriptomic studies, proteomic analysis of Chlamydomonas has led to an increased understanding of its metabolic signaling as well as a growing interest in the elucidation of its phosphorylation networks.

Label-Free Functional Selectivity Assays
2015G protein-coupled receptors (GPCRs) represent the largest class of drug targets. Ligand-directed functional selectivity or biased agonism opens new possibility for discovering GPCR drugs with better efficacy and safety profiles. However, quantification of ligand bias is challenging.
