Peptides regulate most physiological processes and display several other biological activities. Therefore, their importance in the field of biomedical research and drug development is rapidly increasing. However, the use of peptides as therapeutic agents is restricted by some of their physicochemical properties. The development of improved routes of delivery of peptide-based therapeutics is crucial and is crucial and its biomedical value is expected to increase in the near future. The unique properties of hydrogels triggered their spreading as localized drug depots. Several strategies, such as the carbodiimide chemistry, have been used to successfully immobilize bioactive peptide sequences into the hydrogels backbone. Peptide tethering through the so-called \u201cclick\u201d chemistry reactions is also a highly promising, yet underexplored, approach to the synthesis of hydrogels with varying dimensions and patterns. The present review focus on the approaches that are being used for the establishment of chemical bonds between peptides and non-peptidic hydrogels throughout the last decade.<\/jats:p>","DOI":"10.3390\/gels1020194","type":"journal-article","created":{"date-parts":[[2015,10,22]],"date-time":"2015-10-22T03:05:31Z","timestamp":1445483131000},"page":"194-218","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Grafting Techniques towards Production of Peptide-Tethered Hydrogels, a Novel Class of Materials with Biomedical Interest"],"prefix":"10.3390","volume":"1","author":[{"given":"Mariana","family":"Barbosa","sequence":"first","affiliation":[{"name":"UCIBIO-REQUIMTE, Departamento de Qu\u00edmica e Bioqu\u00edmica, Faculdade de Ci\u00eancias, Universidade do Porto, P-4169-007 Porto, Portugal"}]},{"given":"M.","family":"Martins","sequence":"additional","affiliation":[{"name":"Instituto de Investiga\u00e7\u00e3o e Inova\u00e7\u00e3o em Sa\u00fade, Universidade do Porto,  P-4200-135 Porto, Portugal"},{"name":"INEB-Instituto de Engenharia Biom\u00e9dica, Universidade do Porto, P-4150-180 Porto, Portugal"},{"name":"Instituto de Ci\u00eancias Biom\u00e9dicas Abel Salazar, Universidade do Porto, P-4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6018-4724","authenticated-orcid":false,"given":"Paula","family":"Gomes","sequence":"additional","affiliation":[{"name":"UCIBIO-REQUIMTE, Departamento de Qu\u00edmica e Bioqu\u00edmica, Faculdade de Ci\u00eancias, Universidade do Porto, P-4169-007 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2015,10,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"118","DOI":"10.1016\/j.carbpol.2010.11.009","article-title":"Preparation of collagen\u2013chondroitin sulfate\u2013hyaluronic acid hybrid hydrogel scaffolds and cell compatibility in vitro","volume":"84","author":"Zhang","year":"2011","journal-title":"Carbohydr.
