High-resolution imaging of cellular dopamine efflux using a fluorescent nanosensor array.
Intercellular communication via chemical signaling proceeds with both spatial and temporal components, but analytical tools, such as microfabricated electrodes, have been limited to just a few probes per cell. In this work, we use a nonphotobleaching fluorescent nanosensor array based on single-walled carbon nanotubes (SWCNTs) rendered selective to dopamine to study its release from PC12 neurop...
متن کاملSuper-resolution imaging using a camera array.
The angular resolution of many commercial imaging systems is limited, not by diffraction or optical aberrations, but by pixilation effects. Multiaperture imaging has previously demonstrated the potential for super-resolution (SR) imaging using a lenslet array and single detector array. We describe the practical demonstration of SR imaging using an array of 25 independent commercial-off-the-shel...
متن کاملHigh-resolution electroluminescent imaging of pressure distribution using a piezoelectric nanowire LED array
Emulation of the sensation of touch through high-resolution electronic means could become important in future generations of robotics and human–machine interfaces. Here, we demonstrate that a nanowire light-emitting diode-based pressure sensor array can map two-dimensional distributions of strain with an unprecedented spatial resolution of 2.7 mm, corresponding to a pixel density of 6,350 dpi. ...
متن کاملLocalized surface plasmon resonance nanosensor: a high-resolution distance-dependence study using atomic layer deposition.
Atomic layer deposition (ALD) is used to deposit 1-600 monolayers of Al(2)O(3) on Ag nanotriangles fabricated by nanosphere lithography (NSL). Each monolayer of Al(2)O(3) has a thickness of 1.1 A. It is demonstrated that the localized surface plasmon resonance (LSPR) nanosensor can detect Al(2)O(3) film growth with atomic spatial resolution normal to the nanoparticle surface. This is approximat...
متن کاملAssessment of Lymphaticovenous Drainage Through Vascularized Lymph Node Flaps Using Real-Time High-Resolution Fluorescent Imaging.
PURPOSE: Vascularized lymph node (VLN) transfer is a promising treatment option for patients suffering from lymphedema. Despite positive preliminary outcomes, several questions remain unanswered, including mechanism of action and optimal flap design. The purpose of this study was to: 1) evaluate the mechanism of lymph drainage through the VLN flap, and 2) investigate if the number of VLNs impac...
