Smith and Adrian Keller investigate means for efficient cryopreservation of 2D and 3D DNA origami nanostructures and, in particular, the effect of repeated freezing and thawing. It is found that, while the 2D DNA origami nanostructures maintain their structural integrity over at least 32 freeze\u2013thaw cycles, ice crystal formation makes the DNA origami gradually more sensitive toward harsh sample treatment conditions. *<\/p>\n\n\n\n<p>The cryoprotectants glycerol and trehalose are found to efficiently protect the DNA origami nanostructures against freeze damage at concentrations between 0.2 \u00d7 10\u22123and 200 \u00d7 10\u22123m and without any negative effects on DNA origami shape. This work thus provides a basis for the long-term storage of DNA origami nanostructures, which is an important prerequisite for various technological and medical applications. *<\/p>\n\n\n\n<p>NanoWorld <a rel=\"noreferrer noopener\" href=\"https:\/\/www.nanoworld.com\/ultra-short-cantilevers-afm-tips\" target=\"_blank\">Ultra-Short Cantilevers<\/a> for High-Speed AFM <a rel=\"noreferrer noopener\" href=\"https:\/\/www.nanoworld.com\/Ultra-Short-Cantilevers-USC-F0.3-k0.3\" target=\"_blank\">USC-F0.3-k0.3<\/a> were used for the AFM imaging in liquid of the DNA&nbsp; origami sample described in this article.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"667\" height=\"664\" src=\"https:\/\/dhipgo7nn2tea.cloudfront.net\/wp-content\/uploads\/2020\/05\/08140344\/figure-2-from-Cryopreservation-of-DNA-Origami-Nanostructures-by-Yang-Xin-et-al.jpg\" alt=\"Figure 2 from \u201cCryopreservation of DNA Origami Nanostructures\u201d by Yang Xin et al.:\n\nAFM images of triangular DNA origami nanostructures after 32 freeze\u2013thaw cycles measured a) in air and b) in liquid.
