Nanostructured Lipid Carriers-Hydrogels System for Drug Delivery
Nanostructured lipid carriers (NLC) are lipid nanoparticles of the second generation made up of solid lipid matrices mixed with liquid lipids (oils). The hybrid system between NLC and hydrogel may results in the enhancement of each component's synergistic properties in the mechanical strength of the hydrogel and concomitantly decrease aggregation of the NLC. Therefore, the advanced hybrid component development in nanotechnology provides superior functionality in the application of scientific knowledge for the drug delivery industry.

Nanostructure-Modified Electrodes tor Contaminants of Environmental Concern Detection
The contaminants of environmental concern (CECs) are found in substances people all use in the  daily lives such as pharmaceuticals, pesticides, flame retardants, personal care products, and so on. These contaminants pose a threat to human and environmental well being, hence the need for effective methods for the fast and sensitive detection of these contaminants in the ecosystems. The detection of these CECs can be achieved using electrodes modified with novel nanostructures that serve to increase the sensitivity and lower the detection limits.

Nanosized Janus and Dendrimer Particles
Nanosized Janus and dendrimer particles have emerged as promising nanocarriers for the target-specific delivery and improved bioavailability of pharmaceuticals. Janus particles, with two distinct regions exhibiting different physical and chemical properties, provide a unique platform for the simultaneous delivery of multiple drugs or tissue-specific targeting. Conversely, dendrimers are branched, nanoscale polymers with well-defined surface functionalities that can be designed for improved drug targeting and release. Both Janus particles and dendrimers have demonstrated their potential to improve the solubility and stability of poorly water-soluble drugs, increase the intracellular uptake of drugs, and reduce their toxicity by controlling the release rate.

Nanosilica-toughened epoxy resins
Surface-modified silica nanoparticles are available as concentrates in epoxy resins inindustrial quantities for nearly 20 years. Meanwhile, they are used in many epoxy resin formulationsfor various applications like fiber-reinforced composites, adhesives or electronic components; even inspace vehicles like satellites. Some of the drawbacks of “classic” epoxy toughening using elastomersas a second phase, like lower modulus or a loss in strength can be compensated by using nanosilicatogether with such tougheners. Apparently, there exists a synergy as toughness and fatigueperformance are increased significantly. This work intends to provide an overview regarding thepossibilities of nanotoughening with silica, the industrial applications of such epoxy resin formulationsand the most recent research results. Furthermore an overview of other material improvements achieved by the modification of epoxy resins with nanosilica is given.

Nanoscience Delivery Systems Used in Nutricosmetic Sector
Nutricosmetics is a new cosmetics sector that uses an integrated “In and Out” approach. Cosmetic products together with food supplements such as micronutrients (minerals, vitamins), macronutrients (peptides, essential fatty acids), and botanicals (herbal and fruit extracts)  are employed to nourish the skin and reduce skin aging.  Biopolymeric nanoparticles, nanofibers, nanoemulsions, nanocapsules, and colloids are delivery systems applied to improve the bioactive components’ performance in food supplements and cosmetics. The toxicity of nano-sized delivery systems is unclear despite food supplements and cosmetic industries using them.

Nanoporous Stainless Steel Materials for Body Implants
Despite the inadequate biocompatibility, medical-grade stainless steel materials have been used as body implants for decades. The desired biological response of surfaces to specific applications in the body is a highly challenging task, and usually not all the requirements of a biomaterial can be achieved. Nanostructured surfaces have shown intriguing results as cell selectivity can be achieved by specific surface nanofeatures. Nanoporous structures can be fabricated by anodic oxidation, which has been widely studied for titanium and its alloys, while no systematic studies are available for stainless steel (SS) materials.
