Высокоэффективные Воспроизводимые Зонды Для Спектроскопии Комбинационного Рассеяния С Усилением На Острие (TERS)

Abstract

The principal limitation of the use of the Tip Enhanced Raman Scattering spectroscopy (TERS) is due to the lack of reliable scanning probes. The paper presents a simple technique for the fabrication of cantilever-based TERS-probes with highly reproducible characteristics, high performance, reliable and giving sufficient enhancement. The technique is based on the modification of standard scanning probe microscope contilevers by plasma etching and the subsequent formation of a TERS-amplifying region on the tip of probe by deposition of colloidal nanoparticles by dielectrophoresis.
