We introduced a genetically encodable protein spin qubit based on yellow fluoresence protein (YFP).

This is a comprehensive protocol providing extensive details about performing NASR experiment -- a simple yet powerful solution NMR technique allowing quantitative detection of protein internal dynamics on the ns-μs timescales, a range that many loop motions fall in.
Combining material engineering and quantum technologies, we managed to fabricate high-quality diamond membrane heterostructures as thin as 10 nm to be unique platforms for nanophotonics and quantum biosensing applications. In this movie, bacteria expressing green fluorescence protein are swimming near a diamond membrane, which contains nitrogen-vacancy spin qubit sensors.
We developed a biocompatible, versatile, stable, and recyclable surface functionalization method to place biomolecules of interest to the surface of a diamond quantum sensor, which is the first step toward realization of single-molecule quantum biosensing.

In this study, we developed a nanoparticle-assisted detection approach based on NMR spin relaxation, which expands the observation window of intrinsic protein motions from traditional nanosecond regime to microsecond regime. It will allow us to explore protein functionalities that are previously unknown.
We developed a quantitative binding model, named SILC, which describes the dual role that residues play in intrinsically disordered proteins simultaneously as linkers and ligands when interact with nanomaterials or other biomolecules. The SILC model is based on first principle statistical mechanics and explicitly includes cooperativity effects in a fully analytical manner.
We discovered and systematically studied the "silica-philic" propensity of N-methyl motif. This motif is common to many biological molecules including nucleosides that control the flow of genetic information as a form of epigenetic modification.
