We have developed a straightforward method for creating large-area, microscale resolution patterns of functional amines on self-assembled monolayers. The technique utilizes flat elastomeric stamp enriched with photoacid and HD-DVD optical pickup to locally deprotect the N-Boc groups and form chemical patterns with resolution below 10µm. Further details can be found...

Laser formed gratings generate hybrid plasmonic modes
We have employed direct laser writing technique to fabricated large-scale (5 × 5 mm²) gold gratings which generate hybrid lattice plasmon polaritons in the Vis-NIR range. The key element of each grating is a hollow gold microbump that is formed by exposing a thin gold coating with a tightly focused...
A reliable substrate for biochip fabrication
Recently, we have introduced an efficient protocol for UV-controlled photochemical synthesis of stable PEG hydrogel coatings on glass substrates. They proved advantageous for fabrication of protein patterns, especially as cell-adhesive microfeatures for single-cell analysis, as well as for spatially controlled culture. We have demonstrated that the hydrogel-based architectures on glass...
