dc.description.abstract
Many of you, especially those working with more exotic techniques have likely experienced the following: When you explain your technique to someone else, they almost always end up either solidly in the optimistic “Wow, this technique can measure everything!” or in the pessimistic “Can this technique measure anything at all?” camp, but seldomly anywhere between. That certainly has been my experience with atomic force microscopy induced resonance (AFM-IR). By combining a scanning probe tip as transducer with a pulsed, tunable mid-infrared (mid-IR) laser, this technique is able to provide molecular chemical images at 20 nm spatial resolution. This capability makes AFM-IR an exciting tool for chemical characterization across many fields. We can use it to visualize phases withing polymeric materials and chemically identify them [1], [2], perform chemical analysis of individual nanoscale vesicles [3] and measure the distribution of cell components[4], to mention a few.
However, even after a decade working with AFM-IR, I often find myself oscillating rapidly between the above mentioned optimistic and pessimistic camp when it comes to AFM-IRs capabilities: “Yesterday, I took an AFM-IR spectrum of a single molecule and today it isn’t even able to find several percent of my analyte in this micron sized sample? Why?”
There is – of course – an answer to this question. Like with any photothermal spectroscopic measurement, there are mechanical, thermal and optical contributions to the signal. In our work, we’ve started to unravel to be able to understand and predict which AFM-IR configurations and imaging modes work well for a particular analytical task, for a particular sample.
