The Leica TCS SMD FLIM system is part of the Leica TCS SMD Series.

It is a dedicated system for FLIM measurements. These measurements reveal information about the direct neighborhood of molecules on the nanometer scale.

Local conditions can determine folding states that influence the reactivity of molecules. FLIM is also used for binding studies (FLIM-FRET) and to identify natural metabolites under physiological conditions. The SMD FLIM wizard optimizes FLIM measurement conditions and allows the setup of FLIM time series or FLIM stacks

The Leica TCS SMD Series integrates hardware and software from PicoQuant with the high-end confocal system Leica TCS SP5 II. Researchers can now control a complete SMD experiment via one interface, the LAS AF software from Leica Microsystems. The coordination of different hardware and software components for one SMD experiment is now a thing of the past.

Field upgrades of Leica TCS SP5 and SP5 II confocal systems to any of the Leica TCS SMD systems, FCS, FLIM and FLCS, are possible

The picture shows 4 HeLa cells with FRET (Alexa488 and Alexa568) only at the centrosomes (the microtubule organizing centers of the cell): the lifetime of Alexa488 at the centrosomes has decreased to 2,3ns, and the lifetime of Alexa488 outside the centrosomes is 2,7ns. The pseudo colored lifetime is merged with the gray scaled intensity image. Courtesy of Prof. Diaspro, Genua, Italy.
