Micro-dispensing of nano drops with extreme accuracy
Ultra-sensitive, quick response and low power consumption micro-magnetic SI (stress impedance) sensors are vital for critical care applications in the medical arena. Hospitals and other medical facilities, including home-treatments rely on continuous, extremely accurate measurements to optimise treatment.
To ensure reliable readings, dispensed material should either partially or fully fill the inner or outer well repeatably, without ever spilling over the well structure. The Proxima micro analyser, based on semiconductor technology, applies minute volumes of receptor fluids onto a Si-sensor chip with an 0.23 mm needle. Droplets as small as 5 nanolitres can be placed with an accuracy up to 10 um.
