ABOUT US

The Applied Nanomaterials & Devices (AND) research group is led by the professors Dr. Diego Carbalho Barbosa Alves and Além-Mar Bernardes Gonçalves. The main research area is the study and application of nanostructures based on carbon, as well as nanoparticles and nanostructured oxides in general and their applications. We have a leading activity on the synthesis of carbon-based nanostructures such as Graphene, Graphene Oxide, Reduced Graphene Oxide, different types of metallic and oxide-metallic nanoparticles. Thus, beyond the synthesis, our group is searching for the development of nanodevices to be applied as sensors, drug carriers and etc. This group was created in 2013 and has participation in INCT Nanomateriais. Nowadays, our group is composed by three doctoral students, three master students and three undergraduate students. Below is a group photo taken at the Universidade Federal de Mato Grosso do Sul - UFMS.

RESEARCH

SYNTHESIS OF NANOSTRUCTURES

The Graphene Oxide (GO), synthesized using a modified version of Hammers’ method, is the flagship in the synthesis of 2D nanomaterials. Thus, the GO acts as the base for many alterations, such as chemical reduction and embodiment of other nanostructures, like nanoparticles and/or pharmakos. The CVD method is used as route to produce graphene film and molybdenum disulphide. Other types of nanostructures are produced as well, such as: MoO3 nanobelts, Cu, Ag, Ni and Au nanoparticles.

SENSORS

The group has interest in devices capable of responding with changes in one of its properties, when stimulated or exposed to an external agent. All our devices are built with elements containing nanostructures. Currently, a device based on graphene oxide being studied to identify different types of chemical reagents

APPLICATION IN HEALTH / BIOLOGICAL AREAS

The use and application of nanostructures in a health-oriented manner and in biological systems has proven to be feasible. The treatment of leishmaniasis and treatments for the recovery of bone defects are some of the applications in which the group has been working, collaborating with the departments of Pharmacy and Veterinary at UFMS.

ELECTRICAL CHARACTERIZATION OF MATERIALS AND THIN FILMS

Impedance spectroscopy is one of the techniques used for the study and characterization of materials, and reduced GO.

LABORATORY INSTRUMENTATION EMPLOYING ARDUINO

Undergraduate students can begin their contact with experimental physics, developing programming and automation skills, by building simple physics experiments. Therefore, these experiments can be used in teaching or research laboratories.
