This proposal has a research componente and an education one. In the first one, the aim is to produce photodetectors, based on organic semiconductors sensitive to light (such as the rr-P3HT), which allow the conversion of light into electrical signals. The devices will allow the conversion of information carried by light into electrical signals. The final goal will be the implant at the p…

The present project aims to use the silk proteins, fibroin and sericin, in the development of flexible substrates that are efficient in the generation, detection or manipulation of light. For this, initially, fibroin will be used, together with nanoparticles and laser dye, in the preparation of diffraction gratings to study the phenomena of DFB and random laser emission. In the case of se…
Legal blindness is defined by the World Health Organization as a condition of visual acuity less than 20/400 or a visual field of less than 20° in the best-vision eye. According to this definition, in 2010 there were 39 million blind patients worldwide. Retinitis pigmentosa (RP) is the most common cause of hereditary blindness, affecting about 1.5 million people. In this disease, photorec…
Every year more than 5 million deaths and 300 million illnesses result from pathogenic bacterial infection. Given these aggravations, the development of efficient methodologies to identify and quantify foodborne pathogenic bacteria is an urgent need for the feasibility of more rigorous protocols in food safety. In this regard, up-converting energy nanoparticles (UCNPs) are used as highly …

In this short term activities research the main goal is to prepare and characterize carbon quantum dots (CD) following the methodology developed in Araraquara and to evaluate the effects on the photoluminescence properties of the preparation of composites with polymers (PEG/PVA) and clays (Laponite). (AU)
Meter length, lightweight and flexible optically active poly(methylmethacrylate) (PMMA) optical fibers will be used as cylindrical luminescent solar concentrators (LSCs) with unprecedented concentration factors (F>10). PMMA optical fibers coated (bulk fibers) or filled (hollow-core fibers) with lanthanide ions- or dye-containing organic-inorganic hybrid layers will be fabricated and assem…
Despite the indispensable use of agricultural fertilizers to achieve current levels of productivity, chemical nutrients have their effectiveness limited by problems such as ammonia (NH3) volatilization, leaching and/or soil immobilization. One strategy to minimize these problems is to protect the fertilizer with nutrient release barrier materials. Thus, it is desirable that the formed pol…

Foodborne illnesses caused by pathogenic bacteria are a major public health concern. Escherichia coli (E. coli) is one of the most common foodborne pathogens that can cause severe infections in humans. Existing detection methods, such as standard colony counting and culture methods, enzyme-linked immunosorbent assay (ELISA), and polymerase chain reaction (PCR), have several limitations, i…
Lanthanide (Ln3+)-based upconversion nanoparticles (UCNPs) and persistent luminescent particles (PLPs) have unique optical properties that make them attractive for a wide variety of biomedicine applications. On the one hand, UCNPs stand out for their ability to convert low energy NIR photons into higher energy UV-visible photons that allows them to have great advantages over other types o…
Micro and nanomotors have emerged as new environmental remediation platforms, having as the main advantages: movement control in aqueous solution, high efficiency in the degradation of polluting substances and the possibility of reuse. The present project aims at developing micromotors based on nanostructured biomaterials fabricated according to the targets of interest. The micromotors de…
