Biomolecule-mimicking nitrogen-doped carbon dots (N-Cdots) were synthesized from dopamine by a neutralization heat strategy. Fluorescence imaging of various cells validated their nucleus-staining efficiency. The dopamine-mimicking N-Cdots "trick" nuclear membranes to achieve nuclear localization and imaging.

One of the growing challenges in life science research lies in finding useful, descriptive or quantitative data about newly reported biomolecules (genes, proteins, metabolites and drugs). An even greater challenge is finding information that connects these genes, proteins, drugs or metabolites to each other. Much of this information is scattered through hundreds of different databases, abstract...

Assembling nanoparticle-film metallic junctions with a spacing of up to tens of nanometers efficiently turned on fluorophores attached to the film from the quenching status to an intense surface plasmon-coupled emission. Benefiting from this new finding, a fluorescence biosensor was created based on the use of a biomolecule-linked plasmonic assembly as the trigger.

The performance of the original implementation of biomolecule electrostatic simulation using the precorrected-FFT method can be improved via both pre-processing input data and modifications to the implementation. Techniques used for these improvements are described and the resulting effects are analyzed. Potential areas for further speedup are discussed. Thesis Supervisor: Jacob K. White Title:...

Especially biomolecule labeling requires reaction procedures that can be performed under physiological conditions (neutral pH, aqueous solution, ambient temperature) with low reactant concentrations to ensure non-toxic, low background labeling at reasonable time scales while still preserving biological function. Among the plethora of possible reactions only a few generally fit the necessary rea...
