“…Biopolymeric nanomaterials are fabricated with various methodologies such as evaporation of emulsion/ solvent, solvent displacement, complex coacervation, and salting out to have a polymeric nanomaterial formation (Ruhl et al, 2003;Wang et al, 2008;Urban, 2014). Moreover, ionic gels, opposite coulombic charges among polyelectrolytes, and basic self-assembly are different routes for their synthesis based on the electrostatic interactions and amphiphilic features Lima-Tenorio et al, 2015).…”

Nanomaterials-based diagnostics have tremendous advantages over other conventional diagnostic systems in terms of sensitivity, specificity, and portability owing to the unique intrinsic properties of nanomaterials. Thus, there is a substantial need to develop and employ a broad spectrum of nanomaterials for biological and diagnostic applications. In this review, we focus on nanomaterials-assisted disease diagnosis utilizing different techniques such as photoluminescence, colorimetry, fluorescence, electrochemistry, microarray methods, surface plasmon resonance, and surface-enhanced Raman spectroscopy. In these techniques, different nanomaterials, including but not limited to gold and silver materials, metal oxides, and semiconductors, were employed according to their all-purpose chemical and physical properties. As the new properties of nanomaterials are discovered, their contributions to nanobiotechnology applications are vastly increased. In this review, the features of the selected nanobiomaterials, biological tag-modified nanomaterials, and their outstanding applications for the detection of specific biotargets have been summarized according to the latest studies. Nanomaterials contribute to the fields of photo/chemotherapy and biomedical imaging in particular, since all the biological events happen within this size range and beneficiary roles of nanoparticles (NPs) are countless in biomedical applications due to their unique physical and chemical properties. However, due to the necessity of specificity and selectivity, there is a clear ambition to study bioconjugation of NPs to increase the efficiency of the targeted biological applications. Thus, the combination of the specificity and the intrinsic properties of biohybrid NPs facilitate diagnostic and therapeutic applications.

In this research, we prepared hydrophobically modified agarose‐g‐poly(N,N‐dimethylamino‐2‐ethyl methacrylate) via the “grafting from” ATRP technique. First, agarose was hydrophobically modified by acylation of some of its OH groups with palmitoyl chloride. Then, the macroinitiator for ATRP was prepared by acylation of some remaining hydroxyl groups of agarose palmitate with 2‐bromopropionyl bromide. Finally, graft copolymerization of N,N‐dimethylamino‐2‐ethyl methacrylate from agarose macroinitiator was carried out homogenously in dioxane and in the presence of CuCl/PMDETA as a catalyst. All products were characterized by taking FT‐IR and H‐NMR spectra. Kinetic study showed that the ATRP polymerization was first order up to nearly 75% conversion. Investigation of the lower critical solution temperature (LCST) of the graft copolymers in different pH revealed that the solubility and aggregation behavior is completely pH and temperature dependent.

A methacrylate-based copolymer containing side-chain push-pull azo chromophores and adamantyl groups is synthesized and characterized by 1 H NMR, DSC, thermal gravimetric analysis, gel permeation chromatography, and UV-vis. By exploiting its good solubility in a water-immiscible solvent (dichloromethane), azo polymer microspheres are fabricated through the solution dispersion method. Surface relief structures are inscribed on the microsphere surfaces upon exposure to the interference pattern of laser beams at 532 nm. Meanwhile, the shape of the microspheres is stable upon the light irradiation, which is distinct from the submicron-scale colloidal spheres of azo polymers. By using camphene as a porogen, microspheres with the well-developed porous structures are prepared. For the fi rst time, it is observed that pores on the azo polymer microspheres can be modifi ed or even selectively closed upon irradiation with a linearly polarized laser beam.
