Article
In recent years, advances in nanotechnology have raised the specter of developing effective agents for the treatment of high-impact diseases, like gastric cancer, which remains one of the major causes of cancer deaths worldwide. This article reviews advances in the treatment of this pathology using several types of nanoparticles. First, we start wi...

Organic and inorganic nanoparticles show great potential for cancer diagnosis and treatment. Because gastric cancer (GC) represents the second most deadly type of neoplasia worldwide, continued research efforts by scientists and clinicians are essential to improve diagnosis and treatment. This paper reviews significant findings in the area of nanop...
Article
We report the synthesis of a 1:1 β-Cyclodextrin-Phenylethylamine (βCD-PhEA) inclusion complex (IC) and the adhesion of gold nanoparticles (AuNPs) onto microcrystals of this complex, which forms a ternary system. The formation of the IC was confirmed by powder X-ray diffraction and NMR analyses (1H and ROESY). The stability constant of the IC (760 M...

Natural rubber membranes were fabricated using latex from Hevea brasiliensis trees (clone RRIM 600) by casting, and controlling the time and temperature of thermal treatment. Three temperatures were used: 65, 80 and 120 °C and the corresponding annealing times of 6, 8, 10 and 12 h. The centrifugation of the latex produces the constituent phases: so...

Shell-isolated nanoparticles (SHINs) nanostructures provide a versatile substrate where the localized surface plasmon resonances (LSPRs) are well-defined. For SHINEF, the silver (or gold) metal core is protected by the SiO2 coating, which is thicker than the critical distance for minimum quenching by the metal. In the present work, it is shown that...
Article
In this article, we describe how nanoparticles work in photothermally triggered drug delivery, starting with a description of the plasmon resonance and the photothermal effect, and how this is used to release a drug. Then, we describe the four major functionalization strategies and each of their different applications. Finally, we discuss the biodi...

Nanocomposites were prepared from mixture of different concentrations of ferroelectric nanoparticles in an elastomeric matrix based on the vulcanized natural rubber. The morphological characterization of nanocomposites was carried out using Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and Atomic force microscopy (AFM)....
Conference Paper
Full-text available
Tribological properties play an important role in many applications that require low adhesion or non sticking surfaces; therefore, understanding the effect of the surface morphology on adhesion can allow for improved surfaces to be created. In the last 10 years, researchers have paid attention to the impact of the surface roughness on the tribologi...
Article
The first direct experimental evidence for the dependence on the local field enhancement with Raman/fluorescence measurements in the far field is provided. This is achieved using shell-isolated silver nanoparticles permitting recording both the surface-enhanced Raman scattering (SHINERS) and surface-enhanced fluorescence (SHINEF) in one spectrum fr...
Article
Surface‐Enhanced Raman Scattering (SERS) of amino acids has proven a challenging task. The SERS of biomolecules and the formation of a reliable SERS data‐base for medical application has shown to be a very challenging task for two reasons: first, the functional groups in proteins, lipid and sugars do not usually include aromatic moieties or chromo...
Article
Shell-isolated gold nanoparticles provide a reliable, portable, and efficient substrate for luminescence enhancement giving surface-enhanced fluorescence, termed SHINEF. The objectives of the present work are 2-fold: first, tuning the size of the gold core and the shell thickness for maximum SHINEF enhancement, and second, to use the shell isolated...
Article
Heart of gold: Surface-enhanced fluorescence (SEF) is demonstrated with silica-coated gold nanoparticles (SHINEF) that act as "smart dust" on the surface of a Langmuir-Blodgett monolayer. Coating gold nanoparticles of different sizes and shapes opens a wide range of applications for SEF, where the shape of the core with an appropriate thickness of...
Article
The conformation and charge exposure of peptides attached to colloidal gold nanoparticles (AuNPs) are critical for both the colloidal stability and for the recognition of biological targets in biomedical applications such as diagnostics and therapy. We prepared conjugates of AuNPs and three isomer peptides capable of recognizing toxic aggregates of...

In this review, we describe the contribution of peptides to the biomedical applications of metallic nanoparticles. We also discuss strategies for the preparation of peptide-nanoparticle conjugates and the synthesis of the peptides and metallic nanoparticles. An overview of the techniques used for the characterization of the conjugates is also provi...
