Characterization of silver-coated carbon nanotubes dispersed in a specifically formulated dispersant – NanoSperse AQ®
Silver-coated carbon nanotubes (AgCNTs) are well documented for their antibacterial properties. However, aqueous dispersions of AgCNTs could be less effective against bacteria due to their tendency to agglomerate when re-suspended in water. In this study [...]
Reduced bacterial attachment on surface modified hydrophobic fabric surface: a possible approach for safety enhanced packaging material
In the present study, three surface modified fabrics were investigated for their bacterial attachment properties using Salmonella enterica serovar Typhimurium (gram –ve) and Staphylococcus aureus (gram+ve) bacteria. Our results indicate that surface modified fabric show [...]
Bioinspired Layered Materials with Superior Mechanical Performance Via Interface Design

Triggered Assembly of Functional Protein Microdomains in the Cytosol
Biology is unparalleled in the replication of complex structures with diverse functions on the molecular and cellular scale. By using biological materials to assemble structures, process information, and harness energy, the emerging field of synthetic [...]
Assessment by Ames Test and Comet Assay of Toxicity Potential of Polymers Used to Develop a Field Capable Biosensor
Current methods of detecting food-borne pathogens take days to show and confirm results. There is a need for devices that decrease detection time. A field-capable rapid-detection device is being developed and in this study it [...]
Nanowired Mesenchymal Stem cells ameliorate brain pathology exacerbated by diabetes in hyperthermia
Sharma A., Sharma H.S., Feng L., Lafuente J.V., Muresanu D.F., Tian Z.R., Patnaik R., Sharma A., Sharma H.S., Uppsala University, SE
Stem cell transplantation or injection is associated with neuroprotection in stroke and in central nervous system (CNS) injury. However, role of stem cells in hyperthermia induced brain pathology is not investigated so far. Our previous [...]
Localized Controlled Drug Delivery from Mesoporous Implants
There is an ongoing development to improve osseointegration of bone-anchored implants. Despite progress, further improvements are needed in order to allow treatment of patients that suffers from low bone amounts or poor bone quality, and [...]
Carbon Nanotube Matrices for implantable Biofuel Cell design
Glucose biofuel cells are promising candidates to supply implanted electronic devices by converting the chemical energy of glucose, present in body fluids, into electric power. Before such biofuel cells can become realistic alternatives compared to [...]
Enhanced Mechanical and Cytocompatibility Properties of Novel 3D Printed Osteochondral Scaffolds
A series of novel 3D osteochondral computer aided models were designed including a homogenous cross-hatched structure, a bi-phasic structure consisting of a cross hatched pattern and an intersecting rings structure, and a biphasic “key” model [...]
Three-Dimensional Bioprinted Biomimetic Nanocomposite Scaffolds for Osteochondral Regeneration
The current work focused on the manufacture of a three-dimensional biphasic nanocomposite scaffold for osteochondral regeneration. Extrusion-based 3D printing in combination with ultraviolet light induced photocrosslinking allowed for good integration of two disparate polymeric materials [...]
Nanoemulsion with tuneable lipid shell dedicated to targeted delivery of small and biomacro- molecules
Couffin A.C., Bruniaux J., Courant T., Hoang A., Martin C., Fournier A., Mittler F., Texier I., Sulpice E., Auzély-Velty R., Gidrol X., Navarro F., Commissariat à l'Energie Atomique et aux Energies Alternatives, FR
Lipid nanocarriers are considered as suitable carriers to formulate lipophilic drugs, transport them and also deliver more specifically at appropriate biological sites. Based on oil-in-water template emulsion, we have been developing nanodroplets as drug or [...]
Allosteric pathway formation in globin proteins explored with network analysis models
In the context of drug design and protein engineering, understanding the nature of allosteric networks is of particular interest. A pre-condition for successfully developing a rational design of proteins that incorporates allostery is the capability [...]

Daima H.K., Selvakannan PR., Bhargava S.K., Shastry S.K., Bansal V., Siddaganga Institute of Technology, IN
New strategies to fabricate nanomaterials of desired physicochemical properties open up new avenues to use nanomaterials for diverse biological applications. In this context, we demonstrate a green and single step synthesis method to obtain monometallic [...]
Synthesis, characterization and in vitro evaluation of cytotoxicity and antimicrobial activity of chitosan-metal nanocomposites
Chaudhury A., Kaur P., Barnela M., Chopra M., Manujab A., Thakur R., Guru Jambheshwar University of Science & Technology, IN
Engineered multifunctional nanowires as novel biosensing tools for highly sensitive detection and Biosensors as innovative tools for detection of food borne pathogens and environmental virology have been well documented. Advanced applications require appropriate chemical functionalization [...]
Synthesis of of Biopolymeric Nanoparticles Using Supercritical Carbon Dioxide as a Dispersion Medium
The utilization of supercritical fluids (SCFs) can lead to the development of materials with unique chemical or physical characteristics that make them suitable for specialized applications. One such technique is synthesizing with supercritical fluids, where [...]
Nanocrystalline gold-based hydrogen sulfide (H2S) sensor from M13 bacteriophage template
Bio-templated assembly of inorganic materials is a promising technique for facile bottom-up assembly of complex and unique nanostructures at ambient conditions. Here, viral-templated nanocrystalline gold nanowires were synthesized for use in highly sensitive H2S sensors [...]
Combating Dental Caries Via Restorative Materials Containing Antibacterial and Remineralizing Nanoparticles
Melo M.A.S., Cheng L., Zhang K., Weir M.D., Chow L.C., Antonucci J.M., Lin N.J., Lin-Gibson S., Lin-Gibson S., Xu H.H.K., University of Maryland Dental School, US
Dental caries is a wide spread public health problem, despite much effort in health promotion. Caries at the margins of restorations has been the main reason for failure. The development of direct-filling dental materials with [...]
Chemiresistive hydrogen (H2) gas sensor based on viral-templated Pd nanowires
Palladium (Pd) has been widely used for H2 sensing applications because it readily forms a solid solution with hydrogen, modifying electrical resistance. Because the resistance change is diffusion-limited, Pd nanostructured materials with large surface area [...]
