Peptide nanostructures have recently been identified as an important bio-functional nanostructure.  Researchers have demonstrated that modification of these peptide nanostructures can greatly expand their biological applications.

In this work, Minjoong Yoon and colleagues from Chungnam National University, Republic of Korea, have prepared peptide nanoribbons (PNRs) impregnated with a Sn-porphyrin via solvothermal self-assembly.  The resulting nanoribbons are highly fluorescent and thermo-stable.  However, the fluorescence intensity and life-time were selectively affected upon interaction with the nucleotide base sequences of DNA, thus implying that these Sn-porphyrin-PNRs could be useful as a biocompatible DNA sensor.
