    <dcterms:abstract xml:lang="eng">Self-assembled, aggregated, chain-like SnO&lt;sub&gt;2&lt;/sub&gt; nano-assemblies were synthesized at room temperature by a simple wet chemical route within an hour in the presence of DNA as a scaffold. The average size of the SnO&lt;sub&gt;2&lt;/sub&gt; particles and the chain diameter were controlled by tuning the DNA to Sn(II) molar ratio and altering the other reaction parameters. A formation and growth mechanism of the SnO&lt;sub&gt;2&lt;/sub&gt; NPs on DNA is discussed. The SnO&lt;sub&gt;2&lt;/sub&gt; chain-like assemblies were utilized as potential anode materials in an electrochemical supercapacitor. From the supercapacitor study, it was found that the SnO&lt;sub&gt;2&lt;/sub&gt; nanomaterials showed different specific capacitance (C&lt;sub&gt;s&lt;/sub&gt;) values depending on varying chain-like morphologies and the order of C&lt;sub&gt;s&lt;/sub&gt; values was: chain-like (small size) &gt; chain-like (large size). The highest Cs of 209 F g&lt;sup&gt;−1&lt;/sup&gt; at a scan rate of 5 mV s&lt;sup&gt;−1&lt;/sup&gt; was observed for SnO&lt;sub&gt;2&lt;/sub&gt; nano-assemblies having chain-like structure with a smaller size. The long term cycling stability study of a chain-like SnO&lt;sub&gt;2&lt;/sub&gt; electrode was found to be stable and retained ca. 71% of the initial specific capacitance, even after 5000 cycles. A supercapacitor study revealed that both morphologies can be used as a potential anode material and the best efficiency was observed for small sized chain-like morphology which is due to their higher BET surface area and specific structural orientation. The proposed route, by virtue of its simplicity and being environmentally benign, might become a future promising candidate for further processing, assembly, and practical application of other oxide based nanostructure materials.</dcterms:abstract>
