Special Issue Information

Dear Colleagues,

The International Journal of Molecular Sciences is pleased to announce a Special Issue dedicated to the dynamic and rapidly evolving field of bioprinting. The aim of this Special Issue is to capture the latest research findings, technological advances and applications at the intersection of this transformative field. We invite researchers, scientists and practitioners to contribute high-quality original research articles, comprehensive reviews and insightful case studies.

We invite contributions that address advances in 3D bioprinting technologies. Another focus is on biomaterials for bioprinting. Research should address the development and characterization of novel biomaterials, focusing on their biocompatibility, mechanical properties and functional performance in bioprinting applications.

We are also looking for studies that demonstrate the practical applications of bioprinting in tissue engineering and regenerative medicine. This includes case studies and research on bioprinted tissues and organs, as well as applications that demonstrate the potential of bioprinting in regenerative medicine. In addition, we welcome studies on cellular and molecular interactions in bioprinted constructs, investigating how cells interact with each other and with biomaterials in bioprinted structures, as well as the molecular pathways involved in tissue formation and development within these constructs. Finally, we are interested in exploring bioprinted organ and tissue models for disease research, including the creation and use of these models to study disease mechanisms and their application in drug testing, toxicology studies and personalized medicine.

We encourage you to submit papers that showcase innovative research, novel methods and transformative applications that bridge the gap between these exciting fields.

Dr. Rui Vitorino
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Constructing scaffolds with the desired structures and functions is one of the main goals of tissue engineering. Three-dimensional (3D) bioprinting is a promising technology that enables the personalized fabrication of devices with regulated biological and mechanical characteristics similar to natural tissues/organs. To date, 3D bioprinting has been widely explored for biomedical applications like tissue engineering, drug delivery, drug screening, and in vitro disease model construction. Among different bioinks, photocrosslinkable bioinks have emerged as a powerful choice for the advanced fabrication of 3D devices, with fast crosslinking speed, high resolution, and great print fidelity. The photocrosslinkable biomaterials used for light-based 3D printing play a pivotal role in the fabrication of functional constructs. Herein, this review outlines the general 3D bioprinting approaches related to photocrosslinkable biomaterials, including extrusion-based printing, inkjet printing, stereolithography printing, and laser-assisted printing. Further, the mechanisms, advantages, and limitations of photopolymerization and photoinitiators are discussed. Next, recent advances in natural and synthetic photocrosslinkable biomaterials used for 3D bioprinting are highlighted. Finally, the challenges and future perspectives of photocrosslinkable bioinks and bioprinting approaches are envisaged. Full article
