- ItemCombining Nanotechnology and Gas Plasma as an Emerging Platform for Cancer Therapy: Mechanism and Therapeutic Implication(Austin, Tex. : Landes Bioscience, 2021) Rasouli, Milad; Fallah, Nadia; Bekeschus, SanderNanomedicine and plasma medicine are innovative and multidisciplinary research fields aiming to employ nanotechnology and gas plasma to improve health-related treatments. Especially cancer treatment has been in the focus of both approaches because clinical response rates with traditional methods that remain improvable for many types of tumor entities. Here, we discuss the recent progress of nanotechnology and gas plasma independently as well as in the concomitant modality of nanoplasma as multimodal platforms with unique capabilities for addressing various therapeutic issues in oncological research. The main features, delivery vehicles, and nexus between reactivity and therapeutic outcomes of nanoparticles and the processes, efficacy, and mechanisms of gas plasma are examined. Especially that the unique feature of gas plasma technology, the local and temporally controlled deposition of a plethora of reactive oxygen, and nitrogen species released simultaneously might be a suitable additive treatment to the use of systemic nanotechnology therapy approaches. Finally, we focus on the convergence of plasma and nanotechnology to provide a suitable strategy that may lead to the required therapeutic outcomes.
- ItemRolled-up magnetic microdrillers: Towards remotely controlled minimally invasive surgery(Cambridge [u.a.] : Royal Society of Chemistry, 2013) Xi, W.; Solovev, A.A.; Ananth, A.N.; Gracias, D.H.; Sanchez, S.; Schmidt, O.G.Self-folded magnetic microtools with sharp ends are directed at enabling drilling and related incision operations of tissues, ex vivo, in a fluid with a viscosity similar to that of blood. These microtools change their rotation from a horizontal to a vertical one when they are immersed into a rotational magnetic field. Novel self-assembly paradigms with magnetic materials can enable the creation of remotely controlled and mass-produced tools for potential applications in minimally invasive surgery.
- ItemSafe-by-Design part I: Proposal for nanospecific human health safety aspects needed along the innovation process(Amsterdam : Elsevier, 2020) Dekkers, S.; Wijnhoven, S.W.P.; Braakhuis, H.M.; Soeteman-Hernandez, L.G.; Sips, A.J.A.M.; Tavernaro, I.; Kraegeloh, A.; Noorlander, C.W.Safe-by-Design aims to reduce uncertainties and/or increase the human health and environmental safety from already early in the innovation process onwards and will thereby contribute to increased innovation efficiency, economic viability, interdisciplinary collaboration, consumers trust and improve sustainability. Since most innovators or designers are neither toxicologists nor risk assessors, considering human health safety aspects within their innovation process may be challenging. This paper provides sets of questions that can help innovators to assess nanospecific human health safety aspects of their product or material along the various stages of the innovation process. Addressing these questions will facilitate innovators to identify which type of information may support decisions on how to address potential human health risks in the innovation process. The identified information on the human health safety aspects can help innovators to decide if further investments in the product or material are beneficial. It may allow them to rank, prioritize and choose safer alternatives early in the innovation process. This may enable innovators to better anticipate on potential safety issues in an early stage, preventing these safety issues to become an innovation killer in a later stage of the innovation process. This approach to identify potential nanospecific human health risks should be considered as complementary to current regulations. The applicability of this approach was evaluated using a few industrial case studies. To determine if the approach is applicable to the innovation of a broader group of nanomaterials and nano-enabled products, more experience within various industrial sectors is needed.
