By combining state-of-the-art azobenzenes with supramolecular low-molecular-weight gelators, based on cyclic dipeptides, photomodulation of hydrogels was achieved. Photochromic amino acids with structures related to the natural L-phenylalanine were an essential element. The supramolecular hydrogels are multi-responsive towards pH, ions, temperature, and, in particular, light. Hereby the gelator F\u003csub\u003e2\u003c\/sub\u003e-PAP-DKP-Lys can be turned into a sol upon irradiation with green light and within this transition a drug, for example an antibiotic, was released. The further improved supergelator Cl\u003csub\u003e4\u003c\/sub\u003e-PAP-DKP-Lys\u003csub\u003e2\u003c\/sub\u003e is reversibly switchable with red and violet light in the range of 0.2-0.5 % in an isotonic Ringer's solution. At a concentration of 1 %, the hydrogel consisting of Cl\u003csub\u003e4\u003c\/sub\u003e-PAP-DKP-Lys\u003csub\u003e2\u003c\/sub\u003e remains stable in a boiling water bath. Thus, we envision that the enhanced stability of the supramolecular assembly of Cl\u003csub\u003e4\u003c\/sub\u003e-PAP-DKP-Lys\u003csub\u003e2\u003c\/sub\u003e and orthogonal biocompatibility of F\u003csub\u003e2\u003c\/sub\u003e-PAP-DKP-Lys, could enable further applications, spanning from regenerative medicine to electronic devices, besides our future vision towards photopharmacology.\u003c\/p\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 322\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.8 x 8.04 x 5.68 IN\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e April 06, 2020\u003c\/div\u003e\n            ","brand":"BooksCloud","offers":[{"title":"Default Title","offer_id":48632698634489,"sku":"9783832550998","price":169.2,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/2782\/3097\/files\/GmOfeJSiG49783832550998.webp?v=1783138632","url":"https:\/\/bookscloud.io\/products\/photomodulation-of-supramolecular-systems-containing-bioactive-small-molecules-and-biopolymers-paperback","provider":"BooksCloud Book Dropshipping","version":"1.0","type":"link"}
