Protein Microdeposition Using a Conventional Ink-Jet Printer

Protein microdeposition using a conventional ink-jet printer.

Many recent bioanalytical systems based on immunologic and hybridization reactions in a mono- or bidimensional microarray format require technology that can produce arrays of spots containing biospecific molecules. Some microarray deposition instruments are commercially available, and other devices have been described in recent papers. We describe a system obtained by adapting a commercial ink-...

Ink-jet printer heads for ultra-small-drop protein crystallography.

Mass-produced automated piezoelectric driven picoliter delivery systems (printer heads) are fast, inexpensive, and reliable devices that are capable of delivering a very large range of volumes and are ideally suited for high-throughput protein crystallography studies. We used this technology to set up under-oil crystallization experiments with drop sizes from the 200-nL to 3-microL volume range...

Light Fastness of Ink Jet Prints on Modified Conventional Coatings

Water Fastness of Ink Jet Prints on Modified Conventional Coatings

This paper was selected as the 2005 IS&T Itek Award for outstanding original student publication in the field of imaging science and engineering (full version published in JIST 48 #2). In order to produce color ink jet prints with good fastness properties, the use of special, coated papers is generally essential. This study examined the water fastness of ink jet prints using experimental coated...

N-Ink Printer Characterization With Barycentric Subdivision

Printing with a large number of inks, also called N -ink printing, is a challenging task. The challenges comprise spectral modeling of the printer, color separation, halftoning, and limitations of the amount of inks. Juxtaposed halftoning, a perfectly dot-off-dot halftoning method, has proved to be useful to address some of these challenges. However, for juxtaposed halftones, prediction of colo...
