  • Types of nanomaterials in the food packaging: A review   Order a copy of this article
    by Kambiz Sadeghi, Mohammad Shahedi, Mohammadali Najafi, Amireh Sadeghi, Mohsen Shirani 
    Abstract: The advent of nanotechnology has provided remarkable methods for fabricating advanced materials. As such, packaging nanocomposite as one of the research hotspots in the nano-sized science, tends to extend shelf life of fresh food items. Active and intelligent packaging are two great achievements of nanotechnology in which organic and inorganic nanoparticles have showed great effects on the packaging matrix. In particular, nanosensor as an emerging technology can convert data from food items into intelligible signals to communicate with consumers. The objectives of this study are aligned with investigation of various nanostructures commonly used in the packaging industry, and providing an overview of their effects on the packaging performance. This review also elaborates human and environmental safety concerns regarding the application of nanoparticles, and identifies the legislation that has been recently launched.
    Keywords: Nanomaterials; food packaging; Nanosensors; Safety concerns.

    Abstract: The worldwide energy is on the cusp of monstrous alter, driven by an unquenchable request and an increasing mindfulness of the constrained supply and corrupting environment of fossil fuels. More intensive research has been conducted around the world to get different economical energy arrangements. Quantum dot manufactured sun powered cell is the innovation for long run which can give required efficiency to run the solar industry facing with various challenges underneath silicon photovoltaic cell. Quantum dot cells are most flexible frame of renewable vitality since of its unique properties for producing power, warming as well as desalinating water. QDs have bandgaps which are flexible over a wide range of energy levels by changing the dot size. Semiconductor QDs, due to their quantum-based properties, give a modern pathway for controlling energy stream. In this manner, they have the tremendous potential to upgrade the efficiency of solar photovoltaic cells.

  • Biosynthesis of Copper Nanoparticles from Plant extract and Bacteria - A Review   Order a copy of this article
    by Ravindra Sharma 
    Abstract: Copper and its salt have been used for a long time as it is non-toxic, cheaper, antibacterial/antifungal agent, and has high potential in a wide range of catalytic, biological, and sensor application. There has been a great development of various methods for the synthesis of copper nanoparticles, but there have been several limitations in copper nanoparticle synthesis by chemical and physical methods. Thus the interest has been shifted towards the green synthesis of copper nanoparticles which is cheaper, easy, quick, and environment friendly. As there are very few reviews available on the biosynthesis of copper nanoparticles of which most reviews are focused on either application or biosynthesis, not both. Thus, this review provides an overview of recent studies on green synthesis of copper nanoparticles by using plants, bacteria, fungi, and the advantages of using plants over bacteria and fungi for copper nanoparticle synthesis. This review also focuses on the characterization methods of copper nanoparticles and some applications of copper nanoparticles. From this review, it can be concluded that further research on improving the large-scale production and downstream processing technique needs to be done.

  • Preparation of Porous Core Shell Copper Zinc Oxide Nanospheres for Lysozyme Delivery   Order a copy of this article
    by Yusilawati Ahmad Nor, Farahanim Johari, Anand Kumar Meka, Hao Song, Dzun Noraini Jimat, Nur Ayuni Jamal 
    Abstract: Metal oxide nanoparticles such as copper oxide (CuO) and zinc oxide (ZnO) have been widely used in various applications including drug delivery. Recently, there has been great progresses in the development of these metal oxide nanoparticles as carrier for the delivery of antimicrobial biomolecules such as lysozyme. However, very limited amount of biomolecules can be loaded on solid metal oxide nanoparticles along with complex conjugation procedures. Hence, this challenge inspires the development of metal oxide nanocomposites with improved structure to achieve high loading of lysozyme. In this project, copper zinc oxide (CuZnO) nanospheres with porous and core shell structure was prepared by the hard templating method. The core shell nanostructure was obtained at 320 ? where the APF polymer template has been completely decomposed. The nanospheres are having the size of 414 nm, total pore volume of 0.08 cm3/g and range of pore size between 12 nm to 30 nm. The CuZnO can effectively load lysozyme up to 64% by adsorption method. These findings provided new insight on the use of porous metal oxide nanocomposite as an efficient antimicrobial enzyme carrier.

    by Anwesha Sarkar, Debayan Ghosh, Soupam Das, Bhaskara Rao Kokati Venkata 
    Abstract: The current investigation showcases the biogenesis of zirconium oxide nanoparticles by marine yeast, isolated from backwaters of Sundarbans, India. A total of 21 marine yeast isolates were isolated and screened for biosynthesis of zirconium oxide nanoparticles. The potential marine yeasts DSB1 and DSB2 were initially identified by microscopic and biochemical analysis. After spectrophotometric analysis, the ZrO2 nanoparticle DSB1NP was characterised using AFM, FT-IR, SEM and XRD analysis. SEM and AFM analysis suggested that the size of the ZrO2NP DSB1NP was 38 nm and they were spherical in shape. Biogenic DSB1NP showed better metal chelating activity (57%), DPPH scavenging activity (63.8%), and reducing power activity (61.3%) than DSB2NP. DSB1NP has also showed good antibacterial activity against Staphylococcus aureus (22
