Two-photon polymerization is a powerful tool for fabricating three-dimensional micro/nano structures for applications ranging from nanophotonics to biology. To tailor such structure for specific purposes it is often important to dope them. In this paper we report on the fabrication of structures, with nanometric surface features (resolution of approximately… (More)
We use two-photon absorption polymerization to fabricate optically active microstructures that exhibit optically-induced birefringence and dichroism. Our results open the door to new applications in data storage, waveguides and optical circuitry.
Combining a single step biofunctionalization method with a low cost polymeric MEMS platform, an efficient label free aptasensor is developed for direct detection of cancer cells. Utilizing the high binding affinity and specificity of the aptamer AS1411 for the cancer cell marker protein Nucleolin, we could detect as low as 800 cancer cells. Till date there… (More)
We use two-photon polymerization to fabricate microstructures containing the conjugated polymer MEH-PPV. The microstructures preserve the characteristic emission of MEH-PPV, exhibiting waveguiding of such emission when fabricated on top of porous silica substrate.
We measured the two-photon absorption cross-section of Lucirin TPO-L and fabricated complex microstructures using it in acrylate resin. Using quantum chemistry calculations, we relate the nonlinear optical properties of the photoinitiator to its molecular structure.
