Abstract

Among bioactive papers, many multiplexed assays implement methods incompatible with the conventional lateral flow immunoassay (LFIA) carrier material, nitrocellulose. Consequently, its replacement by cellulose has to be considered. This technological breakthrough requires a surface chemistry which ensures both the biomolecules covalent grafting to cellulose and the conservation of their biological activity. To comply with these requirements, the process elaborated in this study implements compounds and methods compatible with biological material. While cellulose chemical modification is usually operated under harsh conditions in organic solvents, the diazonium-based functionalization procedure presented here was performed onto cellulose sheets in water and at room temperature. Paper sheets have been successfully modified and bear different chemical functions which enable grafting of biomolecules by common bioconjugate techniques and to perform LFIAs. More generally, the chemical ways developed in this study are suitable for many biomolecules and would be helpful for any sensitive molecule immobilization onto cellulose sheets.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry B are listed below. This list is neither exhaustive nor exclusive. Antifouling coatings Biocompatible materials Bioelectronics Bioimaging Biomimetics Biomineralisation Bionics Biosensors Diagnostics Drug delivery Gene delivery Immunobiology Nanomedicine Regenerative medicine & Tissue engineering Scaffolds Soft robotics Stem cells Therapeutic devices image block All articles published in Journal of Materials Chemistry B from 2019 onwards will be indexed in MEDLINE®. Articles that primarily focus on providing insight into the underlying science and performance of biomaterials within a biological environment are more suited to our companion journal, Biomaterials Science.
