“…The TiO2 nanoparticle possesses redox selectivity, photocatalyst and tunable magnetic property, whereas the chitosan is said to be more biodegradable and biocompatible [10]. The gold nanoparticles have unique optical, electronic and molecular-recognition properties, which makes them promising a nanomaterial [71,9]. Whilst, the carbon allotropes have their extraordinary strength, thermal conductivity, electrical properties and specifically graphene are transparent helping the nanocomposite to be flexible [73].…”

Cancer is the second leading cause of mortality around the globe, despite the various advancements in science. The success of the cancer treatment lies within early diagnosis and effective therapy making them inseparable. In recent years, there has been an extraordinary development in the field of nanomedicine with the development of new nanoparticles for the diagnosis and treatment of cancer. These researches are generally focused on creating novel nanocomposites for combating cancer. This review will serve as a one-stop arrangement for collating and providing future perspectives about the various nanocomposites based in vitro and in vivo investigations for cancer diagnosis and treatment. From our study, it is revealed that nanocomposite based diagnosis engrosses nanosensors for detection and conjugation of biomarkers, quantum dots, radiolabeling, delivery of contrast agent for better imaging of cancer development. In cancer therapeutics, nanocomposites hold enormous potential in maximizing the benefits of both targeted chemotherapy and photodynamic therapy. This review will encourage the need of in-depth molecular level examination in relation to the cytotoxicity and bio-distribution of the developed nanocomposite should be evaluated in the clinical setting for better understanding. These supplementary researches on nanoncology would help in personalizing cancer theranostics making nanooncology as the future trend.

Hybrid inorganic-organic nanocomposites comprising inorganic nanoparticles and functional polymers are novel and unique class of nanomaterials that synergistically combine and enhance the best properties of inorganic and organic polymers [1][2][3][4]. The potential application fields of such hybrids can include specialty coatings, membranes, sensors, biomaterials, drug delivery systems, catalysts etc. The most common principle concepts of incorporation of inorganic nanoparticles into polymer matrix and the resulting properties of such materials have been reviewed by authors [5][6][7]. Classification of polymer/silicate nanocomposites based on synthetic techniques was suggested in [8]. Although titanium [9,10] and aluminum [11] oxides have been utilized as the inorganic components interacting with functional polymers, the colloid silica due to easy preparation by sol-gel technology [12] is one of the promising inorganic polymeric materials that interacts with polyelectrolytes and forms, so called interpolyelectrolyte complexes (IPEC) -products of interaction of two oppositely charged polyelectrolytes [13][14][15][16][17] Abstract. Interaction between anionic (and cationic) colloidal particles of silica having the particles diameters 12 and 22 nm with synthetic cationic (and anionic) polyelectrolytes of various nature and structure was studied by potentiometric, conductimetric spectroturbidimetric and viscometric methods in aqueous solution. It was shown that the complexation of silica nanoparticles with linear polyelectrolytes leads to formation of mostly stoichiometric interpolyelectrolyte complexes (IPEC) which precipitate from aqueous solution. Casting of water-soluble IPEC followed by thermal treatment gives thin composite films insoluble in water while 'layer by layer' (LbL) deposition of polyelectrolyte components onto silica sols leads to formation of multilayered nano-and microcomposites. The possible mechanism of formation of LbL multilayers consisting of silica sol (SiO2) 'cores' and polyethyeleneimine-polyacrylic acid (PEI-PAA) 'shells' was suggested. It was found that in diluted aqueous solution the radius of gyration, Rg and hydrodynamic radius, Rh mean of LbL particles are independent on LbL concentration and smaller than 100 nm. The zeta potential values of LbL particles are arranged between -10 and -30 mV. The average size of LbL particles estimated by scanning electron microscopy (SEM) is in the range of 200-500 nm. Thermal treatment of LbL multilayers followed by etching of (SiO2) 'core' by HF leads to formation of a series of spherical nanocavities and blob-like microcavities.

Summary: Organic-inorganic hybrid composite materials consisting of poly-(acrylamide) hydrogel (PAAH) and clay minerals such as bentonite, montmorillonite, and kaolin as well as silica and titanium dioxides were obtained by "in situ" synthetic protocol and characterized by swelling measurements, FTIR, SEM, XRD and DSC. Concentration of clay minerals embedded within PAAH is varied from 2.5 to 30 wt.%. The swelling degree of composite hydrogels K s and the constants k and n that characterize the mode of the penetrant (e.g. water) transport mechanism were determined. It was found that the swelling degree of PAAH/Clay minerals is in the range of 7-15 g/g and changes in the following order: PAAH/Bentonite>PAAH/ TiO 2 >PAAH/SiO 2 >PAAH/Kaolin% PAAH/Montmorillonite. The influence of pH, temperature, ionic strength, water-organic solvent mixture, as well as the content of clay minerals and crosslinking agent on swelling-deswelling behaviour of composite hydrogel materials was evaluated. For some PAAH/Clay minerals system the enthalpy of mixing DH m was calculated. The positive values of the DH m indicate that the swelling of composite hydrogel materials in water has the endothermic character. It was demonstrated that PAAH-clay mineral composites can potentially be used as "pigs" for the cleaning of the internal surface of main pipes from debris, sand and asphaltene-resin-wax deposits.
