Robust fluorescent labelling of micropipettes for use in fluorescence microscopy: application to the observation of a mosquito borne parasite infection

10-Aug-2017 | AMANDA E. BALABAN, KEIR NEUMAN, PHOTINI SINNIS, ROBERT S. BALABAN, Journal of Microscopy, 2017

Summary The ability to monitor micropipette injections with a high‐resolution fluorescent microscope has utility for a variety of applications. Herein, different approaches were tested for creating broad‐band fluorescently labelled glass micropipettes including: UV cured glass glues, baked ...

Cloning Mice

01-Aug-2017 | Atsuo Ogura, CSH Protocols, 2017

Viable and fertile mice can be generated by somatic nuclear transfer into enucleated oocytes, presumably because the transplanted somatic cell genome becomes reprogrammed by factors in the oocyte. The first somatic cloned offspring of mice were obtained by directly injecting donor nuclei into ...

Nanoelectronic Coating Enabled Versatile Multifunctional Neural Probes

11-Jul-2017 | Zhengtuo Zhao; Lan Luan; Xiaoling Wei; Hanlin Zhu; Xue Li; Shengqing Lin; Jennifer J. Siegel; Raymond A. Chitwood; C ..., Nano Letters, 2017

Brain function can be best studied by simultaneous measurements and modulation of the multifaceted signaling at the cellular scale. Extensive efforts have been made to develop multifunctional neural probes, typically involving highly specialized fabrication processes. Here, we report a novel ...

Highly Selective Cerebral ATP Assay Based on Micrometer Scale Ion Current Rectification at Polyimidazolium-Modified Micropipettes

31-May-2017 | Kailin Zhang; Xiulan He; Yang Liu; Ping Yu; Junjie Fei; Lanqun Mao, Analytical Chemistry, 2017

Development of new principles and methods for cerebral ATP assay is highly imperative not only for determining ATP dynamics in brain but also for understanding physiological and pathological processes related to ATP. Herein, we for the first time demonstrate that micrometer scale ion current ...

A Multifunctional Frontloading Approach for Repeated Recycling of a Pressure-Controlled AFM Micropipette

04-Dec-2015 | Phillip Roder et al., PLoS ONE, 2015

by Phillip Roder, Carsten Hille Fluid force microscopy combines the positional accuracy and force sensitivity of an atomic force microscope (AFM) with nanofluidics via a microchanneled cantilever. However, adequate loading and cleaning procedures for such AFM micropipettes are required for ...

Voltammetric Determination of Pb, Cu and Hg in Biodiesel Using Gold Screen‐printed Electrode: Comparison of Batch‐injection Analysis with Conventional Electrochemical Systems

26-Nov-2015 | Thiago F. Tormin, Gracy K. F. Oliveira, Eduardo M. Richter, Rodrigo A. A. Munoz, Electroanalysis, 2015

Abstract This article compares the use of batch‐injection analysis (BIA) with a conventional batch system for the anodic stripping voltammetric (ASV) determination of Pb, Cu and Hg in biodiesel using screen‐printed gold electrode (SPGE). The optimized BIA conditions were 200 µL of injection ...

Portable SERS-enabled Micropipettes for Microarea Sampling and Reliably Quantitative Detection of Surface Organic Residues

24-Aug-2015 | Wei Fang; Xinwei Zhang; Yong Chen; Liang Wan; Weihua Huang; Aiguo Shen; Jiming Hu, Analytical Chemistry, 2015

We report the first microsampling device for reliably quantitative, label-free and separation-free detection of multicomponents of surface organic residues (SORs) by means of a quality controllable surface-enhanced Raman scattering (SERS)-enabled micropipette. The micropipette is comprised of a ...

Sensors, Vol. 12, Pages 14983-15008: Scanning Ion Conductance Microscopy for Studying Biological Samples

06-Nov-2012 | Happel, Patrick ; Thatenhorst, Denis ; Dietzel, Irmgard D., Sensors, 2012

Scanning ion conductance microscopy (SICM) is a scanning probe technique that utilizes the increase in access resistance that occurs if an electrolyte filled glass micro-pipette is approached towards a poorly conducting surface. Since an increase in resistance can be monitored before the physical ...

Label-free live brain imaging and targeted patching with third-harmonic generation microscopy [Biophysics and Computational Biology]

12-Apr-2011 | Witte, Stefan; Negrean, Adrian; Lodder, Johannes C.; de Kock, Christiaan P. J.; Testa Silva, Guilherme; Mansvelder, ..., Proceedings of the National Academy of Sciences current issue, 2011

The ability to visualize neurons inside living brain tissue is a fundamental requirement in neuroscience and neurosurgery. Especially the development of a noninvasive probe of brain morphology with micrometer-scale resolution is highly desirable, as it would provide a noninvasive approach to ...
