Complex micro- and nano-structures enable crucial developments in the healthcare remit (e.g., pharmaceutical and biomaterial sciences). In recent times, several technologies have been developed and explored to address key healthcare challenges (e.g., advanced chemotherapy, biomedical diagnostics and tissue regeneration). Electrohydrodynamic atomization (EHDA) technologies are rapidly emerging as promising candidates to address these issues. The fundamental principle driving EHDA engineering relates to the action of an electric force (field) on flowing conducting medium (formulation) giving rise to a stable Taylor cone. Through careful optimization of process parameters, material properties and selection, nozzle and needle design, and collection substrate method, complex active micro- and nano-structures are engineered. This short review focuses on key selected recent and established advances in the field of pharmaceutical and biomaterial applications.

Due to their superior physicochemical features, chitosan thermosensitive hydrogels are multipurpose platforms that are frequently used in the biomedical industry. Many investigations have been conducted recently to modify their pore dimensions, expansion, biodegradability, stimulus-reaction characteristics, and other characteristics in order to better tailor them to the complex craniofacial tissues. They have been the focus of various studies that have attempted to load biological cargos for therapeutic and regenerative uses in the oro-facial tissues.

Farnesol (FAR) belongs to terpenes group and is a sesquiterpene alcohol and a hydrophobic compound, which can be extracted from natural sources or obtained by organic chemical or biological synthesis. Recent advances in the field of nanotechnology allow the drawbacks of low drug solubility, which can improve the drug therapeutic index. Therefore, this study aimed to prepare the FAR inclusion complexes with β-cyclodextrin (β-CD) and hydroxypropyl-β-cyclodextrin (HP-β-CD) through freeze-drying method, proposing their physicochemical characterization, comparing their toxicity, and evaluating their in vitro antibacterial activity.

T cell lymphoma constitutes a complex group of diseases, characterized by heterogeneous molecular features and clinical symptoms, and a dismal outcome no matter the therapeutic strategy chosen. In an attempt to improve patients' survival chances, treatment combinations (chemotherapy, radiotherapy, immunotherapy, gene therapy and thermotherapy) have been tested for their synergistic effects that may dramatically improve outcomes and reduce the side effects of each single modality treatment when therapeutic effects add up while side effects are distributed. In this context, nanoscale drug delivery agents have been developed and exploited to enhance the release of drugs in the treatment of several diseases, showing potential benefits in terms of pharmaceutical flexibility, selectivity, dose reduction and minimization of adverse effects.

In recent years, the use of cationic peptides as alternative drugs with anticancer activity has received attention. In this study, the targeted release of curcumin (Cur) and CM11 peptide alone and together against hepatocellular carcinoma (HCC) was evaluated using chitosan nanoparticles (CS NPs) coated with Pres1 that target the SB3 antigen of HCC cells (PreS1-Cur-CM11-CS NPs). SB3 protein is the specific antigen of HCC and the PreS1 peptide is a part of the hepatitis B antigen, which can specifically bind to the SB3 protein.
