    Nanotechnology, which is one of the new technologies, is the science and technology of designing, constructing and creating of novel nano-scale structure, 1nm to 100 nm in size, with huger quality, novel performance properties, along with fewer defects compared with those of the bulk material (Siqueira et al., 2010). An increasing interest from the scientific community to work with materials in nano metric scale has been observed since the introduction of the concept of nanotechnology by Richard

    Introduction To explain nanocrystalline materials, it should have been explained that “nano” concept at first. Nanostructures are relatively new and interesting subject to investigate, they are in a scale which is between 0-100 nanometers (1 nanometer, nm is equal to 10-9 meter). There are some types of nanostructured materials such as lamellar (1-dimensional), filamentary (2-dimensional) and crystallites (3-dimensional). If grains of the material are made up of crystals, then “nanocrystalline materials”

    nanotechnology. There exist a number of methods to synthesize the nanomaterials, which are categorized in two techniques “top down and bottom up”. Solid state route, ball milling comes in the category of top down approach, while wet chemical routes like sol-gel, co-precipitation, etc. come in the category of bottom up approach. Secondly, characterization of nanomaterials is necessary to analyze their various properties. Therefore, this chapter describes the various methods of synthesis and characterization

    glass silicon chips. This process can bond the biological agent some of its examples are fixed with layer by layer. Polymer coatings charge with the deposition. There are there the main ways for the chemical and physical entrap. Hydro gel is used most of the time is sol-gel. Silicate monomers of polymerization are generated with glassy silica.

    Sol-gel processing is prevented by nanomakes particles which causes pores surface with controlled pore size ranging from few nanometers to tens of nanometers to allow biomolecules loading. The dynamic light scattering (DLS) particle size analyzer (Malvern Instruments, Malvern, UK) will be used for size characterization, polydispersity index (PDI), and the zeta potential of SHMNCs. In addition, SHMNCs can be visualized by scanning electron micrograph (SEM) method (Fig. 9 B-C). The Number of pores

    Phenylcyanamide derivatives can be readily prepared in high yields from the corresponding anilines [17]. The polymer of [Ag(4-NO2pcyd)]n have been prepared by adding of phenylcyanamide in acetone to a solution of AgNO3 in water. The infrared data for the phenylcyanamide ligand and polymer of silver(I) are listed in Table 1. The structure of [Ag(4-NO2pcyd)]n is shown in scheme 2. The identification of C-N vibrations is a very difficult task, since mixing of several bands is possible in this region

    NMOFs from the Gd and BHC shows that it is possible to process unique NMOFs from the same ligand and metal combinations by utilizing the multipurpose metal-ligand coordination modes. The solvothermal approach for the synthesis of NMOFs was reported by two scientists. In their research, they avidly investigated the transformation of the particle morphology during the synthesis process. They added N, N-phenylenebis (salicylideneime) dicarboxylic acid solution which was in DMSO to DMF solution which

    based, obtained from seeds of tamarind. And chemically, it is polysaccharide composed of a chain of (1-4)- -D-glucan having (1-6)- -D xylose units as branches which have partial (1-2)- -D-galactoxylose substitution. Xyloglucan, itself, does not undergo gel formation but dilute solutions partly degraded by galactosidase exhibit gelling properties on heating (temperature dependent gelformation). Besides the use in oral drug delivery, it is also being used for ocular and rectal drug delivery. Xyloglucan

    Introduction In the past years, drug delivery via the nasal route has established itself as a competitor and an alternative route over other routes of administration. It provides a higher degree of patient compliance and drugs can be painlessly self-administered by the patient (Illum, 2003). Drugs administered through nasal route are absorbed rapidly and can reach therapeutically effective plasma levels quickly due to highly permeable membranes and rich vasculature of the nasal cavity (Majithiya
