A low-cost automated micromanipulator
The automated micromanipulator, a device widely used in the life sciences, allows precise three-dimensional positioning of tools and equipment with resolutions at or well below one micrometer, providing cellular-level movement resolution in a highly-controlled manner. The cost of a state-of-the- …

MICROMANIPULATOR-RESONATOR SYSTEM FOR SELECTIVE WEIGHING OF INDIVIDUAL MICROPARTICLES
Over the past decade, MEMS-based cantilever sensors have been widely used in the detection of biomolecules, environmental pollutants, chemicals and pathogens. Cantilever-based sensors rely on attachment of target entities on their surface. The attachment causes either change in surface stress or …

Modelling Hearing Impairment After Ossicular Manipulation and Reducing This Injury
… manipulation: one with direct coupling to a micromanipulator, the other with burr contact to the incudomalleal complex, and assessed electrocochleography (ECochG) outcomes. We then extended this acute model to a recovery model to investigate whether a single intravenous dose of dexamethasone …

LAYER BY LAYER NANOASSEMBLY OF COPPER INDIUM GALLIUM SELENIUM (CIGS) NANOPARTICLES FOR SOLAR CELL APPLICATION
… semiconductor characterization instruments and micromanipulator probing station. It was observed that the conductivity of the films was increased with the deposition of each additional layer. The I/V characteristics were also measured under the light illumination and after annealing to study the …

Methods to enhance embryo quality and recovery rates in superovulated beef cows
… 7 superovulated recoveries were biopsied using a micromanipulator with a microsurgical blade and the sex was determined using PCR techniques. Despite differences in developmental stage between embryos, they were not found to impact sex determination. However, differences in quality grade impacted …
