Abstract

Abstract We describe the design and optimization of a reliable strategy that combines self-assembly and lithographic techniques, leading to very precise micro-/nanopositioning of biomolecules for the realization of micro- and nanoarrays of functional DNA and antibodies. Moreover, based on the covalent immobilization of stable and versatile SAMs of programmable chemical reactivity, this approach constitutes a general platform for the parallel site-specific deposition of a wide range of molecules such as organic fluorophores and water-soluble colloidal nanocrystals.

Abstract

A joint theoretical-experimental study on the optical properties of 5-N-succinimidyl-2.2 -bithiophene (NS-2T), a prototype system for a new class of biomarkers was conducted, and time-dependent density functional theory (TD-DFT) and approximate coupled-cluster single and doubles (CC2) calculations were performed in the ground and excited states. Results showed that CC2 and TD-DFT can very well describe the absorption and photoluminescence energies of the three systems, but the presence of several charge-transfer transitions in the TD-DFT spectrum of NS-2T required the use of a correlated method to validate the TD-DFT results.

Abstract

Singlet and triplet excitation energies in oligothiophenes are analyzed using time-dependent density-functional theory (TD-DFT) with different exchange-correlation functionals. TD-DFT methods underestimate photoluminescence energies but the energy difference between singlet and triplet states shows a trends with the chain-length similar to coupled-cluster singles and doubles model (CC2).
