Attenuated Total Reflection Fourier Transform Infrared spectroscopy (ATR\u2013FTIR) revealed the existence of higher order assembly of Zn<sup>2+<\/sup>: GnRH [6-D-Phe]. Nuclear Magnetic Resonance spectroscopy (NMR) indicated a weak interaction between Zn<sup>2+<\/sup> and GnRH [6-D-Phe]. Atomic Force Microscopy (AFM) showed the existence of GnRH [6-D-Phe] oligomers and fibrils. Molecular Dynamic (MD) simulation of the 10:1 Zn<sup>2+<\/sup>: GnRH [6-D-Phe] explored the interaction and dimerization processes. In contrast to already existing short peptide fibrils, GnRH [6-D-Phe] nanostructures and fibrils form in a Tris-buffered pH environment in a controlled manner through a temperature reduction and a pH shift. The lyophilized Zn<sup>2+<\/sup>: GnRH [6-D-Phe] assembly was tested as a platform for the sustained delivery of GnRH [6-D-Phe] and incorporated into two different oil vehicle matrices. The <i>in vitro<\/i> release was slow and continuous over 14 days and not influenced by the oil matrix.<\/p>\n<p>The article &#8220;<a href=\"https:\/\/doi.org\/10.1038\/s41598-018-29529-w\">Zn2+-triggered self-assembly of Gonadorelin [6-D-Phe] to produce nanostructures and fibrils<\/a>&#8221; by Yordanova Y. <i>et al<\/i>. is licensed under a Creative Commons Attribution 4.0 International License.
