**Preface**

In recent years, the biomedical engineering field has seen remarkable advancements, focusing mainly on developing novel solutions for enhancing tissue regeneration or improving therapeutic outcomes. One of the key components of the latest developments is polymers (natural, synthetic, or blended formulations) due to their indisputable wide range of properties and functionalities that transform them into ideal materials for designing drug delivery systems or scaffolds for tissue engineering. This reprint, devoted to the topic of "Polymer Materials for Drug Delivery and Tissue Engineering", gathers a multidisciplinary collection of articles that merge the knowledge and expertise of worldwide researchers that present their latest research in the field of polymer-based materials. This reprint also brings together articles that report original research on the design and synthesis of novel drug delivery systems and scaffolds or that provide insights into polymer interaction. Polymers are valuable tools for the development of drug delivery systems and biomimetic scaffolds due to their tailorable design, versatility, attractive physiochemical properties, and excellent biocompatibility. With ongoing advancements in polymer science and personalized medicine, polymers hold great promise in revolutionizing the current landscape of the biomedical field, providing a real opportunity for designing personalized biomedical products that can be easily adjusted to meet patients' needs.

This reprint, entitled "Polymer Materials for Drug Delivery and Tissue Engineering", is a tribute to all the dedicated scientists engaged in the field of polymer materials for drug delivery and tissue engineering applications. The editors express their gratitude to all the contributing authors of this Special Issue as their insightful research and commitment to advancing the field have not only elevated the quality of our Special Issue but also contributed significantly to the broader scientific community. Also, we acknowledge all the members of the *Polymers* Editorial Office for their indispensable support and invaluable work in the development of this Special Issue.
