Inorganic Nanobiomaterial Drug Carriers for Medicine
라젠드라 쿠마르 씽,김해원 한국조직공학과 재생의학회 2013 조직공학과 재생의학 Vol.10 No.6
Inorganic nanomedicine refers to the use of inorganic or hybrid nanomaterials and nanosized objects to achieve innovative medical breakthroughs for drug and gene discovery and delivery, discovery of biomarkers, and molecular diagnostics. It is widely believed that nanomaterials will be increasingly used in biomedical applications. However, before these novel materials can be safely applied in a clinical setting, their biocompatibility, biodistribu-tion and biodegradation needs to be carefully assessed. There are a number of different classes of nanoparticles that hold promise for biomedical purposes. Here, we will focus on some of the most commonly studied nanomaterials:Ca-P ceramics, mesoporous silica particles, magnetic nanoparticles, and carbon nanotubes. In this review, we dis-cuss the mechanism of cellular uptake of inorganic nanoparticles and the biodistribution depending on the physico-chemical properties of the particles and in particular on their surface characteristics. Limitations and toxicity issues associated with inorganic nanoparticles in living organisms are also discussed.

Sepideh Pourhashem,Farhad Saba,Jizhou Duan,Alimorad Rashidi,Fang Guan,Elham Garmroudi Nezhad,Baorong Hou 한국공업화학회 2020 Journal of Industrial and Engineering Chemistry Vol.88 No.-
Nanocomposite coatings based on adding inorganic nanofillers in polymer matrix are a new class ofcorrosion protection methods which show superior corrosion resistance and mechanical performancecompared to conventional composite coatings. Inorganic nanomaterials such as metal nanopowders,metal oxides, nano-glassflakes, nitrides and carbides, and nano-calcium carbonates have significantpotential for enhancing the barrier performance of polymer coatings. Herein, the effects of the above-mentioned nanomaterials on the corrosion protection performance of polymer coatings are discussedand a comprehensive review about recent studies on the corrosion resistance of these nanocompositecoatings is provided. This review clearly indicates that the characteristics of nanocomposite coatingsstrongly depend on the type of nanoparticles, morphology, size, specific surface area, the fraction ofnanofillers, the chemical structure, the functional groups, and the interaction between nanoparticles andpolymer matrix. The highest corrosion resistance can be achieved via well-dispersion of nanomaterials inthe polymer matrix and there are various approaches based on the fabrication methods and physical/chemical/mechanical surface treatments to reach this goal. In addition, it is meaningful to developnanocomposite coatings through green approaches without altering the intrinsic properties ofnanofillers and without using toxic chemicals for modification of nanofillers.

Owing to its precise manipulation in nanoscale, DNA as a genetic code becomes a promising and generic material in lots of nanotechnological outstanding exploitations. The nanoscale assembly of nucleic acids in aqueous solution has showed very remarkable capability that is not achievable from any other material resources. In the meantime, their striking role played by effective intracellular interactions have been identified, making these more attractive for a variety of biological applications. Lately, a number of interesting attempts have been made to augment their marvelous diagnostic and therapeutic capabilities, as being integrated with inorganic compounds involving gold, iron oxide, quantum dot, upconversion, etc. It was profoundly studied how structural DNA-inorganic hybrid materials have complemented with each other in a synergistic way for better-graded biological performances. Such hybrid materials consisting of both structural DNAs and inorganics are gradually receiving much attention as a practical and future-oriented material substitute. However, any special review articles highlighting the significant and innovative materials have yet to be published. At the first time, we here demonstrate novel hybrid complexes made of structural DNAs and inorganics for some practical applications.

Research on chiral nanomaterials (NMs) has grown radically with a rapid increase in the number of publications over the past decade. It has attracted a large number of scientists in various fields predominantly because of the emergence of unprecedented electric, optical, and magnetic properties when chirality arises in NMs. For applications, it is particularly informative and fascinating to investigate how chiral NMs interact with electromagnetic waves and magnetic fields, depending on their intrinsic composition properties, atomic distortions, and assembled structures. This review provides an overview of recent advances in chiral NMs, such as semiconducting, metallic, and magnetic nanostructures.

Gautam, Milan,Park, Dae Hoon,Park, Sung Jae,Nam, Kang Sik,Park, Geun Young,Hwang, Jungho,Yong, Chul Soon,Kim, Jong Oh,Byeon, Jeong Hoon American Chemical Society 2019 ACS NANO Vol.13 No.11
<P>Due to antimicrobial resistance and the adverse health effects that follow broad and inappropriate use of antibacterial agents, new classes of antibacterials with broad and strong bactericidal activity and safety for human use are urgently required globally, increasingly so with the onset of climate change. However, R&D in this field is known to be rarely profitable, unless a cost-effective, flexible, and convenient platform that ensures the production of workable candidate antibacterials can be developed. To address this issue, inorganic nanomaterials have been considered for their bactericidal activities, yet further investigations of composition crystalline modifications and/or surface biomaterial coatings are still required to provide effective and safe antibacterial nanoparticles. In this study, we developed a plug-in system comprising a spark plasma reactor and a flow heater under nitrogen gas flow to supply precursor inorganic nanoparticles (Cu-Te configuration) that can be modulated in-flight at different temperatures. From antibacterial and toxicological assays in both <I>in vitro</I> and <I>in vivo</I> models, bactericidal and toxicological profiles showed that the plug-in system-based platform can be used to identify key parameters for producing safe-by-design agents with antibacterial activity [>88% (<I>in vitro</I>) and >80% (<I>in vivo</I>) in antibacterial efficiency] and safety (>65% in <I>in vitro</I> viability and >60% in <I>in vivo</I> survival rate).</P> [FIG OMISSION]</BR>

A new class hybrid poly(2-methoxy aniline) Sn(II)silicate carbon nanotubes composite was synthesized by sol–gel method. The physico-chemical characterization was carried out by Scanning Electron micrograph, X-ray Diffraction, Fourier Transform Infrared, Ultraviolet–Visible Spectroscopy and simultaneous Thermo Gravimetric Analysis. The ion-exchange studies were also carried out to understand the ion-exchange capabilities. The dc electrical conductivity studies reviles its highly conducting nature in the range of 2–3-2 S cm-1. On the basis of distribution studies it was found highly selective for Hg2+. Due to selectivity of the composite, ion selective membrane was prepared and employed it as an indicator electrode in potentiometric titrations.

<P><B>Abstract</B></P> <P>Clay has been widely used since Antiquity. However, its application remains limited due to its low dispersion in water. In this review paper, we introduce amino organophyllosilicates (hereafter: aminoclays), which are synthesized by metal salt and organotrialkoxylane at room temperature. Such organic-inorganic materials have been applied in different areas. There is also the strategy of incorporating aminoclays with another material in order to expand its potential. However, the cytotoxicity of some aminoclays toward mammalian cells has to be reduced before application in practical fields. By evaluating the latest research papers, we take a closer look at the applications of various aminoclays in biological as well as environmental fields.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Preparation/characterizations/library setup of aminoclays [ACs]. </LI> <LI> Applications of [ACs] in biological fields. </LI> <LI> Applications of [ACs] in environmental areas. </LI> <LI> Future research directions of [ACs]. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Alpha and gamma-alumina are materials used as continuous coatings and also in variousfields such asceramics, catalysis and catalytic support, lubricants, and electronics. Boehmite (AlOOH) is used as the rawmaterial for the preparation of alpha and gamma-alumina phases whose properties such as morphology,specific surface area, and porosity, are strongly dependent on the boehmite structure. In this review,various methods for synthesizing boehmite nanoparticles (NPs); including, sol–gel, sedimentation,sewage, and hydrothermal have been reviewed. The most appropriate method for the production ofvarious forms of boehmite is the hydrothermal method. The shape, morphology, and tissue properties ofthe boehmite NPs depend heavily on the conditions of the process, i.e. the pH of the solution, thetemperature, and the reaction time which will be described in this review. Moreover, the application ofboehmite as the catalyst or catalytic support is studied in this review. Therefore, metallic, acidic, basic,ionic, organic, and organometallic catalysts, which are immobilized on boehmite NPs are discussed inthis review.
