Enrichment of cations via bipolar electrode focusing.
We have previously demonstrated up to 5 × 10(5)-fold enrichment of anionic analytes in a microchannel using a technique called bipolar electrode focusing (BEF). Here, we demonstrate that BEF can also be used to enrich a cationic fluorescent tracer. The important point is that chemical modification of the microchannel walls enables reversal of the electroosmotic flow (EOF), enabling cations, ins...
متن کاملTwo-channel microelectrochemical bipolar electrode sensor array.
We report a two-channel microelectrochemical sensor that communicates between separate sensing and reporting microchannels via one or more bipolar electrodes (BPEs). Depending on the contents of each microchannel and the voltage applied across the BPE, faradaic reactions may be activated simultaneously in both channels. As presently configured, one end of the BPE is designated as the sensing po...
متن کاملA Comparison of Bipolar Electrocautery and Chemical Cautery for Control of Pediatric Recurrent Anterior Epistaxis.
OBJECTIVE To compare the outcome of children with anterior epistaxis treated intraoperatively with either bipolar electrocautery or silver nitrate chemical cautery. STUDY DESIGN Case series with chart review. SETTING Tertiary-care pediatric otolaryngology practice. SUBJECTS Children aged 2 to 18 years treated with either intraoperative bipolar electrocautery or silver nitrate chemical cau...
متن کاملEpistaxis management: is medical intervention required for inactive epistaxis?
OBJECTIVES This study aims to discuss the management and the follow-up approach in patients with epistaxis. PATIENTS AND METHODS A total of 367 patients with epistaxis (209 males, 158 females; mean age 52.6±18.3 years; range 18 to 85 years) admitted to the Adult Emergency Department of a university hospital between January 2000 and December 2004 were retrospectively analyzed. RESULTS Of pat...
متن کاملBipolar electrode focusing: tuning the electric field gradient.
Bipolar electrode (BPE) focusing is a developing technique for enrichment and separation of charged analytes in a microfluidic channel. The technique employs a bipolar electrode that initiates faradaic processes that subsequently lead to formation of an ion depletion zone. The electric field gradient resulting from this depletion zone focuses ions on the basis of their individual electrophoreti...
