Electrochemical Bioassay Utilizing Encapsulated Electrochemical Active Microcrystal Biolabels

Analytical Chemistry, 2005
A new approach to perform electrochemical immunoassay based on the utilization of encapsulated microcrystal was developed. The microcrystal labels create a "supernova effect" upon exposure to a desired releasing agent. The microcrystal cores dissolve, and large amounts of signal-generating molecules diffuse across the capsule wall into the outer ...

Electrochemical assay for deoxyribonuclease I activity

Analytical Biochemistry, 2008
A thiolated oligonucleotide having three ferrocenes was immobilized on a gold electrode through the sulfur-gold linkage. This electrode showed a current response based on the redox reaction of the ferrocene moieties and this response was decreased after treatment with deoxyribonuclease I (DNase I), suggesting the disappearance of the ferrocene moieties

Non-Faradaic electrochemical activation of catalysis

The Journal of Chemical Physics, 2008
The use of fuel cells for carrying out oxidation reactions with cogeneration of electrical power and chemicals led, upon cofeeding oxygen and fuel at the anode, to the discovery of the effect of non-Faradaic electrochemical modification of catalytic activity or electrochemical promotion of catalysis.

Electrochemically Active Polymers for Electrochemical Energy Storage: Opportunities and Challenges

ACS Macro Letters, 2013
Polymers have a particularly important place in electrochemical energy storage (EES), not just as the electrolyte, as has been a large focus for solid-state batteries, but also as the electrode. This Viewpoint will introduce how electrochemically active polymers (EAPs) are utilized in electrochemical energy storage with an emphasis on battery cathodes.

Highly Sensitive Electrochemical Methyltransferase Activity Assay

Analytical Chemistry, 2014
A simple and highly sensitive electrochemical DNA methyltransferase (MTase) activity assay is presented in this report. The assay employs the electrocatalytic oxidation of ascorbic acid (AA) by a threading intercalator (N,N'-bis(3-propylimidazole)-1,4,5,8-naphthalene diimide (PIND) functionalized with electrocatalytic redox Os(bpy)2Cl(+) moieties (PIND-
