Product Overview
For a decade now, ProChimia has been a world leader in the area of surface functionalization using a wide variety of self-assembled monolayers (SAMs) on either planar substrates or nanoscopic objects. Capitalizing on our own expertise as well as the technology we developed jointly with leading US universities, we are proud to offer thiol, dithiol, dithiolane, silane, catechol and other ligands that form excellent quality SAMs on metals, glasses, polymers or oxide surfaces. Our offer includes:
(i) ligands that form SAMs resistant to protein and cell adsorption/adhesion
(ii) ligands with functional end-groups to which molecules of interest (proteins, oligopeptides, DNA, small molecules) can be covalently linked
(iii) components for charged, fluorescent, photoswitchable, and electoactive SAMs
(iv) SAMs incorporating Stoddart-like molecular machines (rotaxanes, catenanes)
(v) Molecules that can be used as linkers between SAMs on nanoparticles (for nanoparticle self-assembly)
(vi) Custom-made ligands for virtually any monolayer one can conceive
(vii) A unique selection of functionalized metal nanoparticles (please follow this link to our Nanoparticle Boutique)
Since successful use of SAMs depends crucially on the purity of the constituent molecules, we have developed special synthetic schemes and purification procedures to ensure that our products are as pure as possible – hence, we call them Ultrapure Grade, and we mean it! Needless to say, our products are always fresh when they reach our clients and, to preserve their longevity, are packed in hermetic ampoules under argon.

We invite you to take a minute and browse our online catalog. To learn more about any specific compound and its suggested uses, please click on the 'description' button at the bottom of a corresponding price list. The ordering procedure is explained under 'How to order' buttons. Customers wishing to learn more about the chemistry and specific properties of monolayers are directed to the FAQ page (button at the top of this page) or to our recent review from Current Organic Chemistry (PDF file).

Finally, if the compounds you are interested in are not on our list, please contact us – we may already have them, or we can make them for you on a custom basis. Rapidly, cost-effectively and very, very pure.

Thank you for visiting us,
