Abstract

This Special Issue focuses on the synthesis and characterization of hydrogels specifically used as carriers of biological molecules for pharmaceutical and biomedical employments. Pharmaceutical applications of hydrophilic materials has emerged as one of the most significant trends in the area of nanotechnology. To propose some of the latest findings in this field, each contribution involves an in-depth analysis including different starting materials and their physico-chemical and biological properties with the aim of synthetizing high-performing devices for specific use. In this context, intelligent polymeric devices able to be morphologically modified in response to an internal or external stimulus, such as pH or temperature, have been actively pursued. In general, hydrophilic polymeric materials lead to high in vitro and/or in vivo therapeutic efficacy, with programmed site-specific feature showing remarkable potential for targeted therapy. This Special Issue serves to highlight and capture the contemporary progress in this field.

Abstract

The electrospinning method has the unique ability to produce structured polymeric fibers on the micro or nano scale and to generate novel materials for food and healthcare purposes. The potential of electrospun nanofibers for human healthcare applications is promising, for example, in tissue/organ repair and regeneration, in medical diagnostics and instrumentation, and as vectors to deliver drugs and therapeutics, as biocompatible and biodegradable medical implant devices, as protective fabrics against environmental and infectious agents in hospitals and general surroundings. Furthermore, considerable effort has been directed toward developing scaffolds using biodegradable and biocompatible synthetic, natural polymers or renewable materials that enhance in vitro cell growth, while killing pathogenic bacteria cells. This Special Issue ""Electrospun Polymer Nanofibers for Food and Health Applications” will cover the latest research of electrospun nanofibres in this field including shape-memory electrospun fibre meshes with programmable cell orientation, water-absorbing nano?ber meshes for e?cient removal of excess water from kidney failure patients, and hydrogel nano?bers which can be used as a drug carrier for methylene blue.

Abstract

The aim of this book is to provide an analysis of the main characteristics and applications of hydrogels. Hydrogels are frequently used for manufacturing contact lenses, hygiene products, tissue engineering scaffolds, drug delivery systems, and wound dressings. These materials are useful in everyday life, so publicizing them in both academic and pharmaceutical fields is essential.

Abstract

Nowadays, polymer self-assembly has become extremely attractive for both biological (drug delivery, tissue engineering, scaffolds) and non-biological (packaging, semiconductors) applications. In nature, a number of key biological processes are driven by polymer self-assembly, for instance protein folding. Impressive morphologies can be assembled from polymers thanks to a diverse range of interactions involved, e.g., electrostatics, hydrophobic, hots-guest interactions, etc. Both 2D and 3D tailor-made assemblies can be designed through modern powerful techniques and approaches such as the layer-by-layer and the Langmuir-Blodgett deposition, hard and soft templating. This Special Issue highlights contributions (research papers, short communications, review articles) that focus on recent developments in polymer self-assembly for both fundamental understanding the assembly phenomenon and real applications.

Abstract

This book presents some of the state-of-the-art methods for the study of the gastrointestinal variables affecting oral drug absorption. Practical applications of new in vitro release/dissolution methods are presented, as well as in vitro permeability studies to explore segmental differences. The application of MRI methods for the study of colon physiology is presented to illustrate its potential applications in controlled release dosage form design. Some examples of successful in vitro–in vivo correlations show how implementing the gastrointestinal physiological variables in the new in vitro methods can improve the predictions of in vivo drug product performance. The book contains an updated review of the experimental, computational, and in vivo approaches for measuring intestinal permeability.

Abstract

Biocompatibility refers to the ability of a biomaterial to perform its desired function with respect to a medical therapy, without eliciting any undesirable local or systemic effects in the recipient or beneficiary of that therapy, but generating the most appropriate beneficial cellular or tissue response in that specific situation, and optimizing the clinically relevant performance of that therapy, which reflects current developments in the area of intrinsically biocompatible polymer systems. Polymeric biomaterials are presently used as, for example, long-term implantable medical devices, degradable implantable systems, transient invasive intravascular devices, and, recently, as tissue engineering scaffolds. This Special Issue welcomes full papers and short communications highlighting the aspects of the current trends in the area of intrinsically biocompatible polymer systems.

Abstract

Nanomedicine represents one of the most investigated areas in the last two decades in the field of pharmaceutics. Several nanovectors have been developed and a growing number of products have been approved. It is well known that many biomaterials are able to self-organize under controlled conditions giving rise nanostructures. Polymers, lipids, inorganic materials, peptides and proteins, and surfactants are examples of such biomaterials and the self-assembling property can be exploited to design nanovectors that are useful for drug delivery. The self-organization of nanostructures is an attractive approach to preparing nanovectors, avoiding complex and high-energy-consuming preparation methods, and, in some cases, facilitating drug loading procedures. Moreover, preparations based on these biocompatible and pharmaceutical grade biomaterials allow an easy transfer from the lab to the industrial scale. This book reports ten different works, and a review, aiming to cover multiple strategies and pharmaceutical applications in the field of self-organizing nanovectors for drug delivery.

Abstract

Mucoadhesive polymers are widely used in the design of dosage forms for transmucosal drug delivery to the eye, respiratory, gastrointestinal and reproductive tracts. These routes of drug administration offer a number of advantages including improved drug bioavailability, reduced frequency of administration, and the avoidance for the use of injections.

Abstract

In 2019, we sent out a call for submissions to a Special Issue of Marine Drugs entitled “Marine Chitin 2019”, and we are pleased that this issue has now been published. Over 16 high-impact papers were included in this issue, which we now plan to publish as a book. In addition, we now seek to publish a further Special Issue of Marine Drugs, “Marine Chitin 2020–2021”. As before, we plan to produce an authoritative and exciting issue that will encompass breakthroughs in scientific and industrial chitin and chitosan research. Significant advances in chitin and chitosan research have been made since the 1970s, and current overviews in recent publications involving chitin and chitosan research advances are in need of an update.
