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 ...

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.

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.

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.

Spectral Counting Label-Free Proteomics
2014Label-free proteome quantification methods used in bottom-up mass-spectrometry based proteomics are gaining more popularity as they are easy to apply and can be integrated into different workflows without any extra effort or cost. In the label-free proteome quantification approach, samples of interest are prepared and analyzed separately.
