摘要

Extended and controlled release of more than a single bioactive molecule, simultaneously, from the same biocompatible matrix is challenging to achieve. However, this is important for combating various severe challenges (drug resistance, improved efficacy, etc.) related to drug delivery. In the recent past, the meta-stable trapped air (in the lotus leaf inspired artificial interfaces), which attributed to the extreme water repellency in biomimicked heirarchical (consisted of micro/nano features) interfaces, was unprecedentedly exploited for addressing multiple relevant aspects related to drug delivery (e.g., multiple drug release, tunable drug release, dose control through post-loading of drug molecules, etc.). A biocompatible polymeric material that is (a) synthesized using a one-step covalent and featured gelation of a single polymer and (b) capable of tailoring with a wide range of water wettabilities, was exploited for post loading both hydrophilic and hydrophobic small molecules from a wide variety (less polar, more polar, nonpolar) of organic solvents. Such small molecules loaded polymeric materials continued to display durable nature-inspired bulk wettability and provided simultaneous co-release of two different bioactive drug molecules (i.e., doxorubicin (DOX, anticancer drug) and tetracycline (TC, antibacterial drug)), over 6 months. Moreover, the release extent (from hours to months) of these small molecules was successfully tuned by controlling the water wettability of the single porous polymeric material. The released drug molecules remained bioactive and capable of inhibiting the proliferation of cancer cells (MG-63 (human osteosarcoma) and MDA-MB-231 (human breast adenocarcinoma)) and microorganisms (S. aureus and E. coli). These results provide a facile basis for developing a more potent and multifunctional drug release system for prospective biomedical applications.

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.
