Description:Yet another great example of unique coumarin-4-ylmethyl photocleavablethiol for UV-patterned SAMs applications that is usefulalternative to productCat no. PC 001-m10-0.05orPC 001-m10-0.1 The photo-cleavable protecting groups are called "phototriggers" or "caging groups". Coumarin-4-ylmethyls are phototriggers with higher efficiencies than others such 2-nitro-benzyls, enabling the incident light intensity for the uncaging reaction to be lowered. It leads to minimization of protected functionality damage with maintaining higher spatial and temporal resolution. The coumarin-type cages have been successfully applied to protect phosphates [1, 2], amines [3], carboxylates [4], alcohols and phenols [5]. The N-(11-sulfanylundecan-1-yl)-7-decyloxy-2-oxo-2H-chromen-4-ylmethyl carbamate (Cat no: PC 002-m10-0.05, PC 002-m10-0.1) after uncaging reaction (350 nm irradiation) provides amine group at the surface of SAMs available for interaction or further functionalization. These coumarin-type phototriggers were also applied for modification of SAMs surfaces properties [6-8]. Using irradiation with light to alter the cell adhesiveness of a substrate surface allows for patterning of cell cultures in various shapes and sizes without compromising the bioinert character of the non-irradiated regions.
