Abstract

---

There are various methods based on acoustics used to generate microdrops. High level applications include dispensing living cells / proteins / antibodies / bacteria / DNA; handling of biological reagents to form bio-assays; printing biological materials for microarray or lab-on-a-chip production; printing nanomaterials; printing conductive-inks; the delivery of sample material to beam lines e.g. synchrotrons and XFELs; etc. Typically, acoustic methods are used to deliver droplets with volumes in the pico-liter to low nano-litre range. The aim of this workshop is to describe and discuss one particular acoustic based microdroplet dispensing technology namely Polypico. The technology uses acoustics to dispense liquids from an inexpensive disposable polymer cartridge, with very high precision and accuracy. The use of disposable polymer cartridge completely avoids cross-contamination issues and lends itself well to R&D applications, high precision instrumentation applications, as well as product production applications.
