Effect of ligand density on the spectral, physical, and biological characteristics of CdSe/ZnS quantum dots.

• Samuel J. Clarke, C A Hollmann, Faisal A Aldaye, Jay Nadeau
• Bioconjugate chemistry
• 2008

Chemical modification of the surface of CdSe/ZnS quantum dots (QDs) with small molecules or functional ligands often alters the characteristics of these particles. For instance, dopamine conjugation… (More)

Quantum dots as phototoxic drugs and sensors of specific metabolic processes in living cells

• S. J. Clarke, J L Nadeau, D Bahcheli, Z. Zhang, C A Hollmann
• 2005 IEEE Engineering in Medicine and Biology…
• 2005

When conjugated to CdSe/ZnS nanocrystals (quantum dots), the nucleobase adenine and the neurotransmitter dopamine quench fluorescence emission from in a manner strongly dependent upon the size of the… (More)

Radiation-induced tumorigenesis in preneoplastic mouse mammary glands in vivo: significance of p53 status and apoptosis.

• David X Medina, Linda Stephens, +6 authors Ravmond E. Meyn
• Molecular carcinogenesis
• 1998

In mouse mammary tumorigenesis, p53 mutations facilitate tumorigenesis in concert with other oncogenic alterations. Ionizing radiation enhances tumorigenesis in preneoplastic mammary outgrowth lines… (More)

Quantum dot-FRET systems for imaging of neuronal action potentials

• J L Nadeau, S. J. Clarke, C A Hollmann, D Bahcheli
• 2006 International Conference of the IEEE…
• 2006

Fluorescent semiconductor quantum dots (QDs) can act as energy donors or acceptors with a wide variety of environmentally-sensitive molecules. Conjugation of a single QD to a select number of the… (More)

Nanoparticles and modified fluorescent proteins for imaging of transmembrane potential

• J L Nadeau, C A Hollmann, R Khatchadourian, S. J. Clarke
• 2007 3rd International IEEE/EMBS Conference on…
• 2007

Visual monitoring of membrane potential would be extremely useful for monitoring cell health and activity in any cultured neuron system. On long time scales, cell health in response to depolarization… (More)

Specific blockade by CD54 and MHC II of CD40-mediated signaling for B cell proliferation and survival.

• I S Doyle, C A Hollmann, Ian Nicholas Crispe, Tamara Owens
• Experimental cell research
• 2001

Regulation of B lymphocyte proliferation is critical to maintenance of self-tolerance, and intercellular interactions are likely to signal such regulation. Here, we show that coligation of either the… (More)
