Special Issue Information

Dear Colleagues,

In the last years nanotechnology had a tremendous impact in the development of novel therapeutic strategies. In this context, nanomedicine is now a exponentially growing research field. Emerging in the borderline between medicine and nanotechnology, nanomedicine aims at the comprehensive monitoring, control, construction, repair, defence and improvement of all human biological systems, using engineered nanodevices and new nanomaterials. An important feature shared among nanoparticles is their large high surface-to-volume ratio, making them suitable drug nanocarriers. Moreover, the effectiveness of a therapy relies in targeted release of the therapeutic agent at the injury site, with greater precision and minimized possible side effects. In this context nanoparticles (NPs) play a key role in the combat against cancer, diabetes, infectious diseases and neurodegenerative diseases. Also, nanodelivery systems offer many advantages due to their features: i) can overcome drugs poor solubility and chemical stability; ii) may avoid biodegradation in the human body; and iii) might decrease the resistance of anti-cancer drugs and antibiotics.

Currently NPs are mostly used as nanocarriers, nevertheless, this paradigm is shifting since some were found to display also an intrinsic therapeutic action. Additionally, upon adequate targeting, NPs are a suitable platform for diagnostic, thus allowing imaging at the nano level.

This Special Issue deals with strategies where nanotechnology plays a central role on medical care advance. The issue welcomes different submission types, such as original research papers, short communications, reviews, case reports, and perspectives.

Single domain antibodies from camelids, or nanobodies, are a unique class of antibody fragments with several advantageous characteristics: small monomeric size, high stability and solubility and easy tailoring for multiple applications. Nanobodies are gaining increasing acceptance as diagnostic tools and promising therapeutic agents in cancer and other diseases. While most nanobodies are obtained from immunized animals of the camelid family, a few synthetic nanobody libraries constructed in recent years have shown the capability of generating high quality nanobodies in terms of affinity and stability. Since this synthetic approach has important advantages over the use of animals, the recent advances are indeed encouraging. Here we review over a dozen synthetic nanobody libraries reported so far and discuss the different approaches followed in their construction and validation, with an emphasis on framework and hypervariable loop design as critical issues defining their potential as high-class nanobody sources.

Cancer is the second most common cause of death worldwide, having its origin in the abnormal growth of cells. Available chemotherapeutics still present major drawbacks, usually associated with high toxicity and poor distribution, with only a small fraction of drugs reaching the tumour sites. Thus, it is urgent to develop novel therapeutic strategies. Cancer cells can reprogram their lipid metabolism to sustain uncontrolled proliferation, and, therefore, accumulate a higher amount of lipid droplets (LDs). LDs are cytoplasmic organelles that store neutral lipids and are hypothesized to sequester anti-cancer drugs, leading to reduced efficacy. Thus, the increased biogenesis of LDs in neoplastic conditions makes them suitable targets for anticancer therapy and for the development of new dyes for cancer cells imaging. In recent years, cancer nanotherapeutics offered some exciting possibilities, including improvement tumour detection and eradication. In this review we summarize LDs biogenesis, structure and composition, and highlight their role in cancer theranostics. Full article

Antimicrobial drugs are key tools to prevent and treat bacterial infections. Despite the early success of antibiotics, the current treatment of bacterial infections faces serious challenges due to the emergence and spread of resistant bacteria. Moreover, the decline of research and private investment in new antibiotics further aggravates this antibiotic crisis era. Overcoming the complexity of antimicrobial resistance must go beyond the search of new classes of antibiotics and include the development of alternative solutions. The evolution of nanomedicine has allowed the design of new drug delivery systems with improved therapeutic index for the incorporated compounds. One of the most promising strategies is their association to lipid-based delivery (nano)systems. A drug’s encapsulation in liposomes has been demonstrated to increase its accumulation at the infection site, minimizing drug toxicity and protecting the antibiotic from peripheral degradation. In addition, liposomes may be designed to fuse with bacterial cells, holding the potential to overcome antimicrobial resistance and biofilm formation and constituting a promising solution for the treatment of potential fatal multidrug-resistant bacterial infections, such as methicillin resistant Staphylococcus aureus. In this review, we aim to address the applicability of antibiotic encapsulated liposomes as an effective therapeutic strategy for bacterial infections. Full article
