Special Issue Information

Dear Colleagues,

We are pleased to invite you to participate in this project by contributing with original works or reviews concerning the creation of advanced therapeutic systems for the targeting of drugs and/or imaging agents towards a specific location in the organism.

In particular, the papers of this collection will be selected by carefully choosing those that describe therapeutic systems made from biopolymers—whether natural, semi-synthetic, or synthetic—of proven biocompatibility and biodegradability, if present, with these properties being essential for their potential applicability in the biomedical field.

Specifically, we welcome works concerning the design, production, and chemical–physical, technological, and biological characterization of therapeutic systems capable of accumulating in organs or tissues by exploiting passive and active targeting mechanisms for the treatment of pathologies that heavily affect the quality of life of patients.

We are also very interested in works concerning the possibility of giving a new life to drugs whose administration through conventional formulations is accompanied by various problems such as formulation problems, side effects due to non-specific biodistribution, and inaccessibility to the target site.

Chitosan begins its humble journey from marine food shell wastes and ends up as a versatile nutraceutical. This review focuses on briefly discussing the antioxidant activity of chitosan and retrospecting the accomplishments of chitosan nanoparticles as an anticarcinogen. The various modified/functionalized/encapsulated chitosan nanoparticles and nanoforms have been listed and their biomedical deliverables presented. The anticancer accomplishments of chitosan and its modified composites have been reviewed and presented. The future of surface modified chitosan and the lacunae in the current research focus have been discussed as future perspective. This review puts forth the urge to expand the scientific curiosity towards attempting a variety of functionalization and surface modifications to chitosan. There are few well known modifications and functionalization that benefit biomedical applications that have been proven for other systems. Being a biodegradable, biocompatible polymer, chitosan-based nanomaterials are an attractive option for medical applications. Therefore, maximizing expansion of its bioactive properties are explored. The need for applying the ideal functionalization that will significantly promote the anticancer contributions of chitosan nanomaterials has also been stressed. Full article

Drug delivery through the skin offers many advantages such as avoidance of hepatic first-pass metabolism, maintenance of steady plasma concentration, safety, and compliance over oral or parenteral pathways. However, the biggest challenge for transdermal delivery is that only a limited number of potent drugs with ideal physicochemical properties can passively diffuse and intercellularly permeate through skin barriers and achieve therapeutic concentration by this route. Significant efforts have been made toward the development of approaches to enhance transdermal permeation of the drugs. Among them, microneedles represent one of the microscale physical enhancement methods that greatly expand the spectrum of drugs for transdermal and intradermal delivery. Microneedles typically measure 0.1–1 mm in length. In this review, microneedle materials, fabrication routes, characterization techniques, and applications for transdermal delivery are discussed. A variety of materials such as silicon, stainless steel, and polymers have been used to fabricate solid, coated, hollow, or dissolvable microneedles. Their implications for transdermal drug delivery have been discussed extensively. However, there remain challenges with sustained delivery, efficacy, cost-effective fabrication, and large-scale manufacturing. This review discusses different modes of characterization and the gaps in manufacturing technologies associated with microneedles. This review also discusses their potential impact on drug delivery, vaccine delivery, disease diagnostic, and cosmetics applications. Full article
