This communication describes the development of graphene and graphene reinforced polyvinylester nanocomposites. Low concentration of graphene was incorporated in the polymer matrix with the help of two different solvents. The role of solvent in the nanocomposite was studied. The FTIR spectroscopy and electron microscopy have supported the presence of graphene in the nanocomposites. It was discovered that vehicular medium (i.e., solvent) plays a vital role in the properties of the ultimate nanocomposites. When dimethylacetamide was used as solvent, the morphological analysis suggested the increased toughness while in case when tetrahydrofuran was used as solvent, nanocomposite appeared brittle in nature.

Stimuli-responsive materials are widespread demand among researchers, customize them via chemistry which trigger to induce conformational changes in structures or to take advantage in the form of structural/molecular pedals. The size and dimension oriented materials are being formulated to sense precise environmental changes and can adjust in a predictable manner to make them effective tool for cutting-edge technology. A significant change in the size, structure and properties can be induced by a slight induction of stimulus due to changes in pH, ionic strength, temperature, light or other triggers. The responsive materials can be categorised on the basis of their responsive behaviours during the stimuli for example piezoelectric materials- a swift, linear shape change of materials in response to an electric field and find potential applications in the actuators; electrostrictive and magnetostrictive materials- change in materials size with response to either an electric or magnetic field, and conversely, producing a voltage during stretch and show promising applications for manufacturing of pumps and valves, aerospace wind tunnel, shock tube instrumentation, landing gear hydraulics, and further biomechanics force measurement of ortho-pedic gait and posturography, sports, ergonomics, neurology, cardiology and rehabilitation; rheological materials- electrorheological and magnetorheological fluids that can change state instantly using an electric or magnetic field and uses in vehicle seats, shock absorbers, exercise equipment, and optical finishing; thermo-responsive materials- the materials leading the change in shape with response to heat and/or cold and applicable in couplers, thermostats, automobile, plane and helicopter parts; pH-sensitive materials- materials change colours as a function of pH and promise in paints; electrochromic materials- material to change optical properties by applied voltage and can be used as antistatic layers, electrochrome layers in liquid crystal displays, and cathodes in lithium batteries; responsive gels- reply in term of shrinking or swelling of materials and can be programmed to absorb or release fluids with response to chemical or physical stimulus and applications in agriculture, food, drug delivery, prostheses, cosmetics, and chemical processing.

The supervision of conducting a doctorate degree in interdisciplinary science and technology such as healthcare nanotechnology, a strategic supervisory role is essential. Supervision of such doctor of philosophy (PhD) students immerses in an internationally leading education, research environment and provide a wide range of scientific and complementary training, executed both inter and intra university-private sectors joint supervisions. The focus of this editorial is to bring the criteria to produce trained, highly competent, enthusiastic and creative PhDs by the public and private sectors partnership. The interdisciplinary PhD supervision approach would make significant contributions to designed, constructed and commercialized new technology including personalized healthcare and medical nanodevices.

Nanomaterials play very prominent role in physical, chemical and biomedical engineering applications due their high surface energies. Also the electronic configuration of atoms within the materials is very important since this principally detrmines the type of bonding and thus electrical, optical, luminescent, mechanical and magnetic properties. At nanoscale dimensions, materials exhibit entirely different properties as compared to thieir bulk counterpart. Noble metallic nanoparticles/nanostructures exhibit interesting feature of localised surface plasmon resonant; absorption can be tuned from ultraviolet region to infrared region of electromagnetic spectrum and this field has been developed to deliver potential applications in photonics, optoelectronics, optical-data storage, solar cells, filters, sensors not to mention the considerable scope in medical engineering, such as DNA labeling, tumor and cancer therapy etc.

In today’s world, bio- nanocomposites are becoming increasingly prevalent owing to the extraordinary properties that they possess. Scientists learn to select suitable matrix (e.g. aliphatic polyesters, polypeptides and proteins, polysaccharides, and polynucleic acids) and fillers (e.g. nanotubes, nanofibers, clay nanoparticles, hydroxyapetite and metal nanoparticles) and alter their chemistry and structure to suit the target field. A critical challenge in the design and development of bio- nanocomposites is the adhesion of filler and matrix at their nanointerface. Also, bio- nanocomposites in addition to providing enhanced properties such as mechanical and thermal are biocompatible and/or biodegradable. This makes them one of the most versatile materials available today and thus can be prominently applied to biomedical technologies such as bone restructuring/repair, tissue engineering, dental applications, and controlled drug delivery.

Development of functional tissues often requires spatially controlled growth of cells over 2D surfaces or 3D substrates to maintain their distinct cellular functions; particularly it is essential for culturing anchorage-dependent cells. In this regard, development of new surfaces/substrates with superior surface properties that could control the cell behavior is of great important and extremely necessary for functional tissue engineering as well as to study how the cells spatially recognize and interact with synthetic material systems. Surface patterning is an approach to modify the surface of biomaterials, either chemically or topographically. Both the approaches are well demonstrated in manipulating cell behaviors such as shape, size, orientation, migration, proliferation, and differentiation. In this article, we review various commonly employed methodologies for use in patterning of biomaterial surfaces/substrates and their suitability in controlling cell behaviors.

Polyaniline (PANI) was prepared in emeraldine via chemical oxidation method using CuSO4 as initiating agent. The chemical characterizations were made using UV-vis (ultraviolet-visible spectrophotometry), FT-IR (Fourier transform spectroscopy), TG-DTA (thermo-gravimetric/differential thermal analysis), ESI-MS (electrospray ionization mass spectrometry), XRD (X-ray diffraction), SEM (scanning electron microscopy) techniques. The results revealed the formation of homogeneous, crystalline PANI with sub-micron size particles. The PANI thin film of 0.5 µm thickness has been fabricated using spin coating technique. The resulting PANI film was exposed to controlled humid condition and change in resistance has been recorded. The resistance was continuously decreased from 13.5 to 3.75 MΩ with a linear change in humidity ranging from 3 to 95%. The result was reproducible and checked by repeating observation.

A new type of insulin delivery system capable of better self-regulating the release of insulin was reported in this study. This insulin delivery system was made of a low crosslinked insulin-imprinted hydrogel that exhibited pH-dependent interpolymer interactions between poly(methacrylic acid) (PMAA) and poly(ethylene glycol) (PEG). At acidic conditions (such as pH 3.5), this delivery system resembled a highly crosslinked imprinted hydrogel and demonstrated a relatively slow release due to the formation of the PMAA-PEG complexes, which significantly increased physical crosslinking within the hydrogel interior and largely fixed the imprinted networks. On the contrary, at neutral or basic conditions (such as pH 7.4), this delivery system was comparable to a non-imprinted hydrogel and caused a rapid release resulting from the dissociation of the PMAA-PEG complexes. Unlike previously reported non-imprinted hydrogels and highly crosslinked imprinted polymers, which lack either molecular recognition ability or switchable imprinted networks, this unique insulin delivery system was composed of tunable and low crosslinked imprinted networks, which thereby enabled better self-regulation of insulin delivery.
