Bacterial cell association and antimicrobial activity of a C60 water suspensionDelina Y Lyon
Department of Civil and Environmental Engineering, Rice University, Houston, Texas 77005, USA
Environ Toxicol Chem 24:2757-62. 2005..5 to 3.0 mg/L, respectively. Media with higher salt contents result in the nano-C60 particles aggregating and falling out of suspension; thus, higher salt solutions reduced or eliminated the antimicrobial properties of nano-C60...

Department of Chemistry, Louisiana State University, Baton Rouge, Louisiana 70803 1804, USA
Bioconjug Chem 13:1244-52. 2002..Both dyes were successfully conjugated to oligonucleotide primers, showing their potential for use in near-infrared-based DNA diagnostic applications...
Development of a base set of toxicity tests using ultrafine TiO2 particles as a component of nanoparticle risk managementDavid B Warheit
DuPont Haskell Laboratory for Health and Environmental Sciences, Newark, DE 19714 0050, USA
Toxicol Lett 171:99-110. 2007..To summarize the findings, the results of most of the studies demonstrated low hazard potential in mammals or aquatic species following acute exposures to the ultrafine TiO(2) particle-types tested in this program...

DuPont Haskell Laboratory for Health and Environmental Sciences, Newark, Delaware 19714, USA
Toxicol Sci 97:163-80. 2007..It seems clear that in vitro cellular systems will need to be further developed, standardized, and validated (relative to in vivo effects) in order to provide useful screening data on the relative toxicity of inhaled particle types...
Pulmonary toxicity study in rats with three forms of ultrafine-TiO2 particles: differential responses related to surface propertiesDavid B Warheit
DuPont Haskell Laboratory for Health and Environmental Sciences, Newark, DE 19714 0050, USA
Toxicology 230:90-104. 2007..Thus, the lung toxicity of anatase/rutile uf-3 should not be viewed as representative for all ultrafine-TiO(2) particle-types...
Pulmonary bioassay studies with nanoscale and fine-quartz particles in rats: toxicity is not dependent upon particle size but on surface characteristicsDavid B Warheit
DuPont Haskell Laboratory for Health and Environmental Sciences, Newark, Delaware 19714 0050, USA
Toxicol Sci 95:270-80. 2007..The results demonstrate that the pulmonary toxicities of alpha-quartz particles appear to correlate better with surface activity than particle size and surface area...
