A colorful method to detect C-reactive protein

This photograph shows the colorful results produced by the colorimetric method for the detection of C-reactive protein (CRP), an inflammatory biomarker, used to evaluate cardiovascular risk.The method presents a simple and fast colorimetric method for CRP detection that employs citrate–capped gold nanoparticles (AuNPs) and a CRP binding aptamer as sensing elements. The aptamer, a single-stranded DNA (ssDNA), adsorbs onto the surface of the AuNPs. In the presence of the CRP, the ssDNA releases from the AuNPs surface to interact preferentially with the protein to form guanine-quadruplexes. The exposure of the unprotected AuNPs to buffer salts leads to aggregation and subsequent color change from red-wine to blue-purple, seen by the naked eye. The AuNPs aggregation was monitored using UV–Vis spectroscopy and the CRP concentration in the samples could be correlated with the aggregation ratio (A670nm/A520nm). A linear sensing range of 0.889–20.7 μg/mL was found. The detection limit (LOD) was 1.2 μg/mL which is comparable to the typical clinical cutoff concentration in high-sensitivity CRP assays (1 μg/mL) and lower than the detection limit of nephelometric methods used in clinical practice. This method can provide a fast (5 min analysis time), simple, and sensitive way for CRP detection.

Keep your enemies close!

Do you know that cancer cells don’t live alone? In fact, they turn native enemies into friends… To grow, invade and even metastasize to different tissues, cancer cells produce regulatory signals to recruit various stromal cell types and modulate their behavior to act as pro-tumorigenic agents. In this image, cancer cells in a spheroid (in red) were able to invade through a human protein-based hydrogel, chemotactically attract the surrounding bone-marrow mesenchymal stem cells (in green) and directly interact with them. This “friendship” usually helps cancer cells in chemotherapy resistance.

Little drops make the mighty ocean

Someone once said “Little drops of water, little grains of sand, make the mighty ocean and the pleasant land.” So is the case with the cells in our body. Little units of life that make up all our tissues and organs. In this image, one can see the hundreds of cells that composed a single piece of human tissue (in this case, the amniotic membrane) looking like drops in the waves of the ocean.

Miniaturizing big things

The same way that the small electronic chip arrays feed and control the device that is in front of you, a technology called “organ-on-a-chip” have emerged as miniaturized microfluidic chips able to simulate the structure of human tissues. Organ-on-a-chips can be built in clear pieces of silicone with variable design (usually poly(dimethyl siloxane), as the one showed in the photo) where cells can grow. The main particularity of these 3D models is that they work with continuous fluid flow, providing nutrients and applying an in vivo-like shear stress to reproduce tissue function in a more realistic way. This microfluidic chip combines biomaterial science with organ-on-a-chip technology to recapitulate osteosarcoma tumor invasion.

Microneedles are arrays of needle-like projections in the micrometre range. The image emphasizes the pyramidal structure of the micron-sized needles in the patch, designed to painlessly puncture skin in a minimally-invasive manner. Biopolymeric microneedles are promising systems constructed from safe and biocompatible polymers and can be used as carriers for the release of therapeutic cargo across the epidermal layer, or as vehicles for interstitial fluid absorption to retrieve crucial biomarkers in the diagnosis of specific pathologies.

Stroma Everywhere: The Close Relationship between Tumor Cells and the Surrounding Stroma

Understanding and recapitulating native pancreatic ductal adenocarcinoma (PDAC) tumor-stroma niche is crucial to accelerate the discovery of new and effective therapies. Herein, we leverage in superhydrophobic surfaces to bioengineer core-shell tumor-stroma 3D PDAC models that mimic the close tumor-stroma relashionship mediated by the physical differential organization where cancer and stroma compartments are patterned according to their unique native tumor architecture in which tumor core is enveloped by the fibrotic stroma. The presented F-actin fluorescence micrograph show the established 3D tumor model composed by cancer cells and spread cancer-associated fibroblasts, a key population of PDAC stroma.

Your turn to roll the dices!

Time is up! Environmental disasters are getting more frequent, powerful and dangerous. It’s undeniable that we have to change to a more sustainable lifestyle before it’s too late to win the game. As scientists, it’s our chance to play a role in society and contribute to a better future. Our green composites developed in CICECO, with many end applications ranging from the automotive, furniture and electronics, are not only entirely made of renewable materials but also biodegradable. They are certainly the way to go to replace the non-recyclable and non-biodegradable conventional composites based on fossil resources. We realise that our contribution to solve the environment issues is only a little piece of a much broader game, but a much needed one. It’s our time to roll the dices!

A Kiln with History

In the photo we can see the kiln that was used for ten thousand years to produce ceramic. This one was in use until the late 1980s and was built in 1947. The boxes in the photo are refractory boxes, saggars, and were placed in a circle along the wall in order to fill the entire kiln. These boxes enclosed the porcelain piece and protected it from combustion impurities. Placing the porcelain in the kiln was difficult to perform and required a skilled person. The numbers on the saggars corresponded to the employee´s number that filled the saggar. When the kiln was filled, the door was sealed with bricks and raw clay. The kiln was heated at a temperature of 1350 ºC and the process took 40h. This kiln is currently in exhibition in the Vista Alegre Museum.

Reflecting the Past, Reflecting the Present

Advanced materials science has shaped the development of civilizations since the dawn of mankind. Stronger materials for tools and weapons allowed society to spread, conquer and prosper. In fact, materials are so important to mankind that entire periods of time were defined by the predominant material used. However, considering the health of the world we live in, we have reached a point that we need desperately to reflect on materials through time, to understand the role they are supposed to assume in the future. In Aveiro, everything happens around the large amount of water next to the sea, called Ria. It acts as a large mirror that reflects the traditions of several generations living in an environment fully immersed in the ceramics production. There is a better place to rethink material science? The photography challenges the public to look at an old and emblematic ceramic factory reflection in the present, and imagine the material science role in the future.

The Three Plates

The photo shows a cross-section of three different plates: the one in front is porcelain, the second one is earthenware and third one is stoneware. Porcelain is composed by 45% kaolin, 25% feldspar, 25% quartz and 5% clay. Earthenware is made of 40% kaolin, 30% silica, 15% clay and 15% calcite and stoneware is made of 27% kaolin, 30% feldspar, 25% silica, 15% clay and 3% talk. The different compositions are primordial to shape its characteristics and influence its hardness and visual characteristics such as whiteness. These plates are currently in exhibition in the Vista Alegre Museum.

Treasure in a bottle

In this picture is possible to admire one of nature’s treasures. Beaches, such as Barra, offer us the most wonderful colored and shaped small stones. We have learned how to take advantage of this creation and to turn it into complex objects or in this case, simple ones such as bottles. Bottles, like this one, often save messages and secrets or in this case can keep an historical symbol of the Aveiro coast. The Barra lighthouse is not only one of the tallest in Europe, but also a guide to where the Aveiro lagoon finally finds the sea. Here we can note how such a majestic structure can be preserved in a small piece of glass.

White Gold

Salt production has played a major role in the economy of Aveiro for approximately one thousand years. Its extraction is entirely artisanal, resulting from the evaporation of seawater by the sun and the wind. Marnoto is the person responsible for collecting the salt by hand from the saltpans. Compared to other regions in the country, salt from Aveiro is richer in the compound β-ionone, which gives it its pleasant violet aroma. A staple in most kitchens and dishes around the world, it is also used in laboratories for scientific research. CICECO, the largest Portuguese institute in the field of materials science, is located near the saltpans of “Marinha Santiago da Fonte”, which were acquired by the University of Aveiro in 1993. The proximity of CICECO to these saltpans makes them an ideal visiting place for students.
