Ebook "Biomedical nanotechnology: Methods and protocols" is to provide an overview of biomedical nanotechnology, from the conception of novel materials in the laboratory to the application of such structures in the clinic. After a brief introductory chapter, the first section consists of protocol chapters which provide practical information on the synthesis of a variety of solution-phase and surface-bound nanomaterials and their application in sensing, imaging, and/or therapeutics; most chapters provide step-by-step instructions and insight into overcoming possible pitfalls and challenges.

TiO2 has strong photocatalytic activity, which can oxidize and decompose impurities on surfaces and in the air. Therefore, TiO2 is used as an additive in the self-cleaning coating and paint industries. In this work, SiO2 is used in the TiO2/SiO2 mixture as the nucleus to homogenize the dispersion components. TiO2 and SiO2 nanoparticles are synthesized by the sol-gel method combined with ultrasound that suits the size range of 10-30 nm.

This paper presents the results of immersion assay on antifouling performance of a fluoropolymer nanocomposite coating on the steel substrate using natural seawater medium in laboratory. The fluoropolymer nanocomposite coating was composed in the presence of reinforcement additives, including organically modified titanium dioxide (m-TiO2), organically modified zirconium dioxide nanoparticles (m-ZrO2) and antifouling agent of Cu2O nanoparticles and fluoropolymer.

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.

Polyurethane foams have good shock-absorbing properties. This article discusses the study of the physical, dynamic analysis, and microstructure of filled polyurethane foams (PUR). We used mineral fillings nanoparticles of titanium dioxide (TiO2 ) and calcium carbonate (C1) to support and strengthen the foam cell structure to develop shock absorption and thermal resistance properties. Dynamic mechanical analysis (DMA) and compression tests compared the mechanic characterization results with different modelling approaches.

Metal-oxide nanoparticles have reached a wide range of applications in the last ten years. Titanium dioxide nanoparticles stand out with their unique crystal structure and near-perfect physical and chemical properties at nanoscales (crystal size between 10–100 nm). It has created many applications with its white pigment, semiconductor state, and effective photocatalytic properties, but the synthesis of these nanoparticles is very damaging to nature.

TiO2 and Fe-doped TiO2 nanoparticles were prepared by hydrothermal method in order to study the effect of ion doping (Fe) on enhancing photocatalytic activity of TiO2. The band gap, morphology and specific surface area of TiO2 and Fe-doped TiO2 were investigated by step-wise increasing Fe3+ concentrations from 0.05 to 1.00 wt.%.

The use of nanoparticles (NPs) has increased in recent years and consequently they are being released into the environment. The final destination of most NPs is the aquatic environment due to washing up by rain waters. Fish (n = 120) were exposed to different concentrations (0, 1, 5, and 25 mg/L) of aluminum-oxide (Al2O3), copper-oxide (CuO), and titanium-dioxide (TiO2) NPs for 14 days and 14 days of depuration period (no NP in water). Following NP exposures, activities of Na,K-ATPase, Mg-ATPase, Ca-ATPase, and acetylcholinesterase (AChE) in the brain and muscle were measured.

Titanium dioxide (TiO2) and carbon black (CB) nanoparticles (NPs) have biological effects that could aggravate pulmonary emphysema. The aim of this study was to evaluate whether pulmonary administration of TiO2 or CB NPs in rats could induce and/or aggravate elastase-induced emphysema, and to investigate the underlying molecular mechanisms.
