This paper first presents a theoretical background of DEP phenomena and then reviews recent works of the present author, which were aimed to develop nanomaterial-based sensors, such as a CNT gas sensor and a ZnO nanowire photosensor, using DEP fabrication technique. It is also demonstrated that DEP technique enables self-formation of interfaces between various nanomaterials, which can be also applicable as novel sensing transducers.

“Objectives: BAHA implantation surgery in a pediatric population is usually done in two-stage surgeries. This study aims to evaluate the safety and possible superiority
of the one-stage over the two-stage BAHA implantation and which one would be the best standard of care for our pediatric patients.
Methods: A retrospective chart review of 55 selleck patients operated in our tertiary care institutions between 2005 and 2010 was conducted. The actual tendency in our institutions, applied at the time of the study, is to
perform a one-stage surgery for all operated patients (pediatric and adult), except for patients undergoing translabyrinthine surgeries for cerebellopontine tumor excision. These patients indeed had a two-stage insertion. 26 patients underwent one-stage surgery (group I) while 29 patients had a two-stage (group 11) BAHA insertion. A period of 4 months was allowed for osseointegration before BAHA processor fitting. As for the safety assessment of the one-stage surgery, we compared both groups selleck screening library regarding the incidence and severity (minor, moderate and major) of encountered complications, as well as the operating time and follow-up. The operating time of the two-stage surgery includes the time of the first and of the second stage.
Results: The mean age at surgery was 8.5 years old for the group I and 50 years old for the group II patients.
Selleck ACY-241 There was no difference in the incidence of minor (p = 0.12), moderate (p = 0.41) nor severe (p = 0.68) complications between groups I and II. Two cases of traumatic extrusion were noted in the group I. Furthermore, the one-stage BAHA implantation requests a significantly lower operating time (mean: 54[32-100] min) than the two-stage surgery (mean: 79[63-148] min) (p = 0.012). All pediatric cases of BAHA insertion were performed in a one day surgery. The mean postoperative follow-up was 114 and 96 weeks for groups I and II respectively (p = 0.058).
Conclusions: One-stage BAHA insertion surgery in the pediatric population is a reliable, safe and efficient therapeutic option that allows a good result in a significantly lower operating time compared to the two-stage insertion and is achieved in a one day surgery. It could therefore be considered as a standard of care for pediatric patients. (C) 2012 Elsevier Ireland Ltd. All rights reserved.”
