Development and Applications of Bioresorbable Materials

Dear Colleagues,

Bioresorbable materials are a special class of materials that can fully degrade and dissolve in the body after fulfilling the designed functions. There are two main kinds of bioresorbable materials: bioresorbable polymers and bioresorbable metals, which are also known as biodegradable metals. Bioresorbable polymers have a long history and many of them have been approved for use by the U.S. Food and Drug Administration (FDA), e.g., poly-L-lactide (PLLA), poly(D,L-lactide) (PDLLA), poly(glycolic acid) (PGA) and their copolymers. Bioresorbable metals have been developed quickly with the preceded mechanical properties and durability. Magnesium (Mg), iron (Fe), and zinc (Zn) have so far been the three main bioresorbable metals. Bioresorbable medical devices made from these bioresorbable materials are designed to be temporarily implanted in the human body and would therefore avoid a second removal surgery, as is required for classic medical devices. This provides a unique opportunity to engineer different molecules and electrical and sensing components into implantable biodegradable systems. This Special Issue aims to present the latest works in the development and various applications of absorbable materials, to explore the most important findings, to explore more clinical applications, and to provide perspectives on the future direction of this field.

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 250 words) can be sent to the Editorial Office for assessment.

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. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). 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.
