Special Issue Information

Dear Colleagues,

Nanotechnology is a branch of science concerned with the design, fabrication, and application of nanoparticles (NPs) and nanomaterials. Introduced by Feynman in 1959, the fields of nanoscience and nanotechnology have been subjected to growing interest from scientists in almost all research areas. They have not only been integrated into chemistry, engineering, agriculture, biology, and materials science, but have also been used to produce nanostructured medical devices and nanotherapeutics. As a result of this interest, NPs began to be commercialised in the early 2000s and exposed to popular opinion, facing both praise and criticism from the public. Indeed, despite the extent of documented research, there is still a gap in knowledge regarding the risk to human health consequent to exposure to NPs.

In this Special Issue of Nanomaterials, we welcome original research articles and reviews regarding nanoparticle applications and their effects on human cells. Particularly, articles should focus on the harmful effects of (a) inorganic-based NPs, (b) carbon-based NPs, (c) organic NPs, including lipid, polymer, and hybrids, (d) nanomaterials, and (e) engineered NPs on human cells. Further potential research areas include (but are not limited to) the following:

  • drug delivery;
  • medical therapies and diagnosis;
  • biology and biotechnologies;
  • agriculture and food industry;
  • industrial processes;
  • renewable energies;
  • engineering and bio-engineering.

All contributions related to underlying cell viability and cytotoxicity, mechanisms of toxicology, and related evaluation models for analyzing NP risk effects are welcome.

We look forward to receiving your contributions.

As nanocarriers of a new generation, biomimetic nanovesicles are an emerging class of therapeutic tools whose surface is integrated or fabricated with biomaterials capable of mimicking the biological features and functions of native cells. Thanks to this, biomimetic nanovesicles, in particular, those made by plasma membrane moieties, possess greatly improved biocompatibility, high target specificity, a long retention time, and minimal undesired immune responses. For these reasons, a multitude of progenitor cells including cancer ones were employed as templates to generate biomimetic or membrane-camouflaged nanovesicles hosting different therapeutic compounds. In this contribution, different membrane-derived biomimetic vesicles (M-NVs) were generated by osmotic lysis or plasma membrane isolation approaches from normal and cancer cell lines and assayed against in vitro models of human glioblastoma. M-NVs were compared in their cellular internalization degrees of DNA and proteins, morphologically and molecularly characterized, expressing an extracellular membrane-associated marker. Then, Rose Bengal (RB), a photoactivable drug characterized by a relatively low cellular uptake, was incorporated into nascent glioblastoma-derived M-NVs and finally administered to homotypic receiving cells, showing an increased degree of internalization as well as induced cytotoxic effects, even in the absence of photodynamic direct stimulation. Similar results were also obtained assaying lyophilized M-NVs loaded with RB. In conclusion, M-NVs generated by cell membranes effectively deliver several cargoes, including therapeutic molecules, maintain functionality after lyophilization, and show significant internalization effects, making them a promising strategy for therapeutic applications against human glioblastoma cells.

Photodynamic therapy (PDT) has developed as an efficient strategy for cancer treatment. PDT involves the production of reactive oxygen species (ROS) by light irradiation after activating a photosensitizer (PS) in the presence of O2. PS-coupled nanomaterials offer additional advantages, as they can merge the effects of PDT with conventional enabling-combined photo-chemotherapeutics effects. In this work, mesoporous titania nanorods were surface-immobilized with Chlorin e6 (Ce6) conjugated through 3-(aminopropyl)-trimethoxysilane as a coupling agent. The mesoporous nanorods act as nano vehicles for doxorubicin delivery, and the Ce6 provides a visible light-responsive production of ROS to induce PDT. The nanomaterials were characterized by XRD, DRS, FTIR, TGA, N2 adsorption–desorption isotherms at 77 K, and TEM. The obtained materials were tested for their singlet oxygen and hydroxyl radical generation capacity using fluorescence assays. In vitro cell viability experiments with HeLa cells showed that the prepared materials are not cytotoxic in the dark, and that they exhibit photodynamic activity when irradiated with LED light (150 W m−2). Drug-loading experiments with doxorubicin (DOX) as a model chemotherapeutic drug showed that the nanostructures efficiently encapsulated DOX. The DOX-nanomaterial formulations show chemo-cytotoxic effects on Hela cells. Combined photo-chemotoxicity experiments show enhanced effects on HeLa cell viability, indicating that the conjugated nanorods are promising for use in combined therapy driven by LED light irradiation.
