Electrocatalytic amplification of nanoparticle collisions at electrodes modified with polyelectrolyte multilayer films

AD Castañeda, TM Alligrant, JA Loussaert, RM Crooks - Langmuir, 2015 - ACS Publications
We report electrochemical catalytic amplification of individual collisions between ∼57 nm
diameter Pt nanoparticles (Pt NPs) and 12.5 μm diameter Au ultramicroelectrodes modified …

Multistep galvanic exchange synthesis yielding fully reduced Pt dendrimer-encapsulated nanoparticles

RM Anderson, DF Yancey, JA Loussaert, RM Crooks - Langmuir, 2014 - ACS Publications
Here we outline a new method for synthesizing fully reduced Pt dendrimer-encapsulated
nanoparticles (DENs). This is achieved by first synthesizing Cu DENs of the appropriate size …

Electrochemical properties of metal-oxide-coated carbon electrodes prepared by atomic layer deposition

JA Loussaert, SE Fosdick, RM Crooks - Langmuir, 2014 - ACS Publications
Here we report on the electrochemical properties of carbon electrodes coated with thin layers
of Al 2 O 3 and SnO 2 . These oxide films were deposited using atomic layer deposition (…

Microspectroscopic investigation of the membrane clogging during the sterile filtration of the growth media for mammalian cell culture

X Cao, JA Loussaert, Z Wen - Journal of Pharmaceutical and Biomedical …, 2016 - Elsevier
Growth media for mammalian cell culture are very complex mixtures of several dozens of
ingredients, and thus the preparation of qualified media is critical to viable cell density and final …
