Special Issue Information

Dear Colleagues,

This Special Issue aims to highlight the transformative role of nanomaterials and biomaterials in the field of biomedicine, exploring their applications and impact on healthcare technologies. Nanotechnology has emerged as a promising frontier, enabling precise manipulation at the nanometer scale for diagnostic, therapeutic, and imaging purposes. At the same time, biomaterials play a key role in designing biocompatible platforms and promoting advances in drug delivery, tissue engineering, and regenerative medicine.

The contributions in this Special Issue aim to disseminate cutting-edge research that addresses challenges and presents innovative solutions at the intersection of nanotechnology and biomaterials in biomedicine. Key themes include the development of multifunctional nanocarriers for drug delivery, the integration of nanomaterials to improve diagnostics and therapeutics, and the use of biomaterials in tissue engineering for regenerative medicine applications. In addition, ethical considerations and safety aspects related to the use of these advanced materials are welcomed.

By focusing on diverse perspectives, this Special Issue aims to provide a comprehensive overview of recent advances, promising trends, and future directions in harnessing the potential of nanomaterials and biomaterials to revolutionize biomedicine. The fusion of knowledge from multidisciplinary research fields contributes to the ongoing discussion about translating these innovations into tangible clinical applications.

The Influence of the Variable Wettability Characteristics of Layers on the Transport of Nanoparticles in the Context of Drug Delivery in Skin Structures

by Mariola M. Błaszczyk, Łukasz Przybysz and Aleksandra Budzyń

Abstract

The rapid development of nanotechnology has offered the possibility of creating nanosystems that can be used as drug carriers. The use of such carriers offers real opportunities for the development of non-invasive drug delivery through skin structures. However, in addition to the ability to create suitable nanocarriers, it is also necessary to know how they move through dermal layers. The human skin consists of layers with different wettability characteristics, which greatly complicates how introduced substances move through it. In this work, an experimental study of the diffusion process of nanoparticles through partitions with different wettability properties was carried out. Conventional diffusion tests using Franz chambers were used for this purpose. We quantified how the wettability of the barrier, the number of layers, and their mutual configuration affect the transport of nanoparticles. Based on the results, an analysis of the phenomena taking place, depending on the wettability of the partition, was carried out. A model relationship was also proposed to determine the effective diffusion coefficient, taking into account the influence of the wettability and porosity of the barrier. Full article

Targeted Clindamycin Delivery Systems: Promising Options for Preventing and Treating Bacterial Infections Using Biomaterials

by Dagmara Słota, Josef Jampilek and Agnieszka Sobczak-Kupiec

Abstract

Targeted therapy represents a real opportunity to improve the health and lives of patients. Developments in this field are confirmed by the fact that the global market for drug carriers was worth nearly $40 million in 2022. For this reason, materials engineering and the development of new drug carrier compositions for targeted therapy has become a key area of research in pharmaceutical drug delivery in recent years. Ceramics, polymers, and metals, as well as composites, are of great interest, as when they are appropriately processed or combined with each other, it is possible to obtain biomaterials for hard tissues, soft tissues, and skin applications. After appropriate modification, these materials can release the drug directly at the site requiring a therapeutic effect. This brief literature review characterizes routes of drug delivery into the body and discusses biomaterials from different groups, options for their modification with clindamycin, an antibiotic used for infections caused by aerobic and anaerobic Gram-positive bacteria, and different methods for the final processing of carriers. Examples of coating materials for skin wound healing, acne therapy, and bone tissue fillers are given. Furthermore, the reasons why the use of antibiotic therapy is crucial for a smooth and successful recovery and the risks of bacterial infections are explained. It was demonstrated that there is no single proven delivery scheme, and that the drug can be successfully released from different carriers depending on the destination. Full article
