Special Issue Information

Dear Colleagues,

Nanomaterials have recently become one of the most active research fields in the areas of engineering, chemistry, solid state physics, biotechnology and biomedicine. One reason for this interest is that nanomaterials display novel and often enhanced properties compared to traditional materials, which opens up the potential for new technological applications. The use of nanomaterials in the biomedical field presents many revolutionary opportunities in the fight against all kinds of cancer, cardiac and neurodegenerative disorders, infection and other diseases. The nanoparticle platforms that have been extensively explored for biomedical applications are predominantly either purely inorganic or organic materials. For example organic nanomaterials such as nanocrystals, liposomes, dendrimers, hyper-branched organic polymers, micelles and polymeric hydrogel nanoparticles have been widely used as imaging and therapeutic agents. Recently, inorganic nanomaterials such as quantum dots, superparamagnetic iron oxide nanoparticles, metallic nanoparticles and metal oxides have also attracted great attention for biomedical applications.

In another relevant example, hybrid nanoparticles are composed of both inorganic and organic components that can not only retain the beneficial features of both inorganic and organic nanomaterials, but also possess unique advantages over the other two types. For instance, the ability to combine a multitude of organic and inorganic components in a modular fashion allows for systematic tuning of the properties for biomedical applications. Hybrid nanoparticles have been proposed for the targeted release of diagnostic agents and drugs, and even as stimuli responsive nanocarriers to enhance therapy selectivity. The combination of these materials with current efforts to identify genes, proteins and metabolites implicated in human disease and use system biology approaches to develop new prognostic tools and more targeted therapies for patients, will dramatically impact healthcare in the coming years.

This Special Issue focuses on the use of organic/inorganic or hybrid nanomaterials for biomedical applications. We invite full papers, communications and reviews covering one or several of the topics included in (or related to) the keywords below.

We report the design, fabrication and characterization of a carbon nanotube enabled open-type X-ray system for medical imaging. We directly grew the carbon nanotubes used as electron emitter for electron gun on a non-polished raw metallic rectangular-rounded substrate with an area of 0.1377 cm2 through a plasma enhanced chemical vapor deposition system. The stable field emission properties with triode electrodes after electrical aging treatment showed an anode emission current of 0.63 mA at a gate field of 7.51 V/μm. The 4.5-inch cubic shape open type X-ray system was developed consisting of an X-ray aperture, a vacuum part, an anode high voltage part, and a field emission electron gun including three electrodes with focusing, gate and cathode electrodes. Using this system, we obtained high-resolution X-ray images accelerated at 42–70 kV voltage by digital switching control between emitter and ground electrode. Full article

Abstract: Nanogels are attractive biocompatible materials, which mimic bio-environment, enable delivery of m ulti-drugs, absorb water to swell and gradually release the drug payloads at the site of application. While nanogels have several advantages as biomedical materials, they are often not well-suited for consistent production. Advancements in 3D printing technology has led to high precision, high efficiency, high reproducibility, and convenient operations, which may allow for the creation of patient-specific and rationally-designed biomedical materials or devices including nanogels. Here, we propose to review and summarize recent development of nanogels using 3D printing technology.

Abstract: Lung gene therapy for cystic fibrosis disease has not been successful due to several challenges such as the absence of an appropriate vector. Therefore, the optimal delivery of newer therapeutic approaches to airway epithelial cells demands suitable non-viral systems in order to reduce potential host immune responses. In this work, we describe the formulation and the bio/physicochemical investigation of biocompatible and biodegradable polymeric nanoparticles (NPs), including PLGA and chitosan (animal and vegetal), as a novel method for the safe and efficient delivery of CFTR-specific locked nucleic acids (LNAs).

Title: Fabrication of precisely-defined nanomaterials via advanced manufacturing techniques for translational applications

Abstract: Nanomaterials have shown great potentials in biomedical applications. Most nanomaterials are generated via bottom-up technologies—techniques that assemble nanomaterials from small building blocks such as chemical molecules. These methods, while useful by producing nanomaterials in a large batch, have very limited flexibility in controlling materials properties such as size, surface property, cargo loading, etc. As a contrast, advanced manufacturing techniques such as photolithography, soft lithography and layer-by-layer assembly allows fabricating nanomaterials with highly controllable features, enabling unique translational studies and applications. Here in this work, we will review the existing technologies that employ advanced manufacturing techniques for generating nanomaterials with precisely defined characteristics, as well as their translational application. We will also address the advantages of these highly controlled nanomaterials as compared to conventional materials in biomedical applications.

Abstract: In a recent report, the World Health Organisation (WHO) classified antibiotic resistance as one of the greatest threats to global health, food security, and development. Methicillin-resistant Staphylococcus aureus (MRSA) remains at the core of this threat, with persistent and resilient strains detectable in up to 90% of S. aureus infections. Unfortunately, there is a lack of novel antibiotics reaching the clinic to address the significant morbidity and mortality that MRSA is responsible for. Recently, nanomedicine strategies have emerged as a promising therapy to combat the rise of MRSA. However, these approaches have been wide-ranging in design with few attempts to compare studies across scientific and clinical disciplines. This review seeks to reconcile this discrepancy in the literature, with specific focus on the mechanisms of MRSA infection and how they can be exploited by bioactive molecules delivered by nanomedicines, in addition to utilisation of the nanomaterials themselves as antibacterial agents. Finally, we discuss targeting MRSA biofilms using nano-patterning technologies and comment on future opportunities and challenges for MRSA treatment using nanomedicine.
