status

As usual, a manufacturer web page is not really suitable for an encyclopedia article. I cleaned it up a little, removed a line of pure advertising, adjusting the bias towards the form of dispensing the company sells, simplifying the sentence structure, and removing many unnecessary words. I would have continued, but I realized a major problem: the overwhelming amount of the text is about dispensing liquids and semi-solids in general, not about microdispensing. There is in fact essentially no material about the actual subject. Maybe the material here can be used elsewhere, after cleaning it, and a proper article written. And in any case it needs references other than the web site. It needs references providing substantial coverage from 3rd party independent published reliable sources, print or online, but not blogs or press releases, or material derived from press releases. A textbook would be a good choice here. I'll be back to see progress . DGG (talk) 23:48, 20 July 2009 (UTC)

I came here to fix a mis-spelling and ended up with a good example of how to eat up more time than I have :-| It still needs a lot of work and review by someone more familiar with the subject (than I am). Then there's the problem with it being generally about fluid through nozzles instead of microdispensing... AlanM1 (talk) 09:35, 25 August 2009 (UTC)

Proposed expansion: life-science applications and microarray fabrication

I have a professional affiliation with M2-Automation, a manufacturer of microdispensing equipment. I am therefore proposing this change on the talk page rather than directly editing the article.

The current article focuses mainly on industrial dispensing, adhesives and inkjet-related processes. I would like to suggest expanding it to include established life-science applications of microdispensing, particularly microarray fabrication and highly parallel biochemical assays.

The proposed addition would rely primarily on independent peer-reviewed literature rather than manufacturer sources.

Life-science applications

Microdispensing is used in life-science research and biotechnology to deposit small volumes of biological reagents onto substrates or into microstructured reaction sites. Applications include the fabrication of protein and DNA microarrays, biochemical assays, biosensors and high-throughput screening platforms.

Both contact and non-contact printing methods are used for microarray fabrication. Contact methods include solid and quill pins, while non-contact approaches include piezoelectric and inkjet-based dispensing.

Piezoelectric capillary dispensing has also been used for the non-contact fabrication of functional protein microarrays.

Microarray fabrication and high-throughput screening

Microdispensing can enable biological reagents to be arranged at high spatial density while reducing the amount of sample required for individual reactions.

For example, a 2023 peptide–HLA screening study used non-contact microarray printing to dispense picolitre-scale peptide and HLA solutions into microstructured arrays. The study used more than 5,000 spots per array and generated more than 30,000 binding curves.

Would editors consider this an appropriate expansion of the article? I would be happy to provide additional independent references or revise the proposed wording. M2-Automation (talk) 08:32, 28 August 2026 (UTC)
