INL advances skin engineering with the European network NETSKINMODELS

Advances in skin engineering research are being made at the INL as part of the NETSKINMODELS COST Action. This European network is dedicated to advancing skin engineering and modelling by developing improved cell-based and computational skin models, with the goal of reducing reliance on animal testing. Ana Ribeiro, staff researcher at INL, highlights the contributions of Alfaro-Moreno’s research group: “At INL, we are developing skin-on-chip models, which are advanced microfluidic devices designed to replicate the structure and function of human skin. These models have the potential to transform research by providing more reliable and human-relevant data while supporting the 3Rs principle: reducing, refining, and replacing animal testing.” Samantha Costa, one of the next-generation researchers benefiting from the NETSKINMODELS educational initiatives, has joined INL for her PhD research. Samantha’s work takes a further step towards the practical applications of these models, from testing cosmetics and nanoparticle safety to skin microbiome interactions. By focusing on sustainable and ethical research practices, Samantha concludes that “INL’s innovations aim to benefit science, industry, and society.” “This work not only advances dermatological research but also helps prepare the next generation of scientists,” adds Ana Ribeiro. “Through initiatives like NETSKINMODELS, we are ensuring that Europe remains at […]

INL researchers are exploring new ways to predict breast cancer metastasis

INL researchers are exploring new ways to predict breast cancer metastasis

A research project called 3DSecret is exploring innovative methods to predict breast cancer metastasis by analysing tumour cells circulating in the bloodstream. 3DSecret focuses on understanding how these cells contribute to cancer spreading to distant organs, which is the primary cause of mortality in breast cancer patients. Breast cancer metastasis often occurs via the hematogenous route, i.e. through the bloodstream. The presence of circulating tumour cells (CTCs) provides an opportunity to study the disease through blood samples rather than invasive tissue biopsies. Using specialised devices, INL researchers can isolate these tumour cells from blood samples. The next step involves cultivating individual CTCs in an artificial culture system, in the lab, designed to mimic their natural environment. Data from these cultures are then analysed using artificial intelligence algorithms. By examining the genetic profiles of the tumour cells and the substances they secrete, the project aims to identify unknown drivers of breast cancer metastasis. Recently, the project technical coordinator, Miguel Xavier, was at ‘90 Segundos de Ciência’, a series of science communication episodes with daily broadcasts on the Portuguese public radio Antena 1. Miguel is confident about the broader implications of this project, “this research could provide insights into the relationship between […]

How microalgae could transform the way we produce photonics

How microalgae could transform the way we produce photonics

Photonic crystals, essential for controlling and manipulating light, are key components in advanced technologies such as lasers and sensors. However, their production is typically expensive, requiring sophisticated cleanroom facilities. Researchers at INL are exploring innovative alternatives by leveraging structures naturally produced by microalgae. Pedro Braga Fernandes, a PhD candidate at INL, explains “Our group works on photonic structures, and we try to draw inspiration from nature for that. I work with microalgae called diatoms. These diatoms produce a silica exoskeleton with an organisation resembling a photonic crystal, similar to those we create in the cleanroom.” This natural resemblance of diatoms with photonic crystals could bring a new solution for more sustainable production methods. Unlike traditional fabrication methods, the use of diatoms eliminates the need for costly cleanroom environments, reducing both financial and environmental impacts. Pedro Braga Fernandes highlighted the nano-patterned silica potential applications, “This enables easy integration of the structures produced by the algae into essential technologies, ranging from biosensors to quantum systems”. This unique approach not only has the potential to reduce production costs but also offers a sustainable alternative for developing photonic technologies. By using natural processes, researchers at INL aim to unlock new possibilities across a wide […]

Phages – A dual solution to the Antimicrobial Resistance (AMR) Crisis

Phages – A dual solution to the Antimicrobial Resistance (AMR) Crisis

Antimicrobial resistance (AMR) has emerged as one of the most pressing global health threats of our time, directly causing and contributing to millions of deaths worldwide, as reported by the World Health Organization (WHO). Beyond the human toll, the economic impact is staggering. By 2050, AMR could add $1 trillion in healthcare costs annually and slash global gross domestic product (GDP) by up to $3.4 trillion per year by 2030. But amidst these daunting figures, a beacon of hope has appeared – bacteriophages (phages). In an era where AMR poses one of the greatest challenges in modern medicine, phages, viruses that specifically target bacteria, represent a revolutionary alternative to traditional antibiotics. A recent milestone in this field has been Portugal’s approval of customised bacteriophage therapies in hospital settings, setting Portugal to be only the third European country, alongside Belgium and France, to approve until now a guiding regulation for these new therapies (INFARMED, I.P. deliberation No. 112/CD/2024, November 15, 2024) for complex bacterial infections. This decision aligns closely with INL’s cutting-edge research on phages.  Dr. Sanna Sillankorva, a tenured staff researcher from the Bañobre Research Group at INL has been instrumental in this progress. Her work focuses on isolating and […]

Nanoscale analysis with DNA-graphene origami

Nanoscale analysis with DNA-graphene origami

In a recently published study in Advanced Materials Interfaces, INL researchers have developed a new sensor that merges DNA origami with graphene to achieve unique accuracy in detecting molecular motion. Nieder’s group at INL, together with Alpuim’s group (INL) and Thorsten-Lars Schmidt  (Kent State University), developed this innovative sensor that could have significant potential for applications in medicine and environmental monitoring. The sensor combines DNA origami structures and a graphene layer functionalised to interact with fluorescent markers. These markers emit light, and their fluorescence behaviour – specifically its duration – changes based on their proximity to the graphene. By applying electrical signals, researchers can control this distance, enabling them to track movements as small as two nanometres. “The novelty here is that we can actually gate the graphene and sense the effects of this electrostatic approach in the fluorescent behaviour of the fluorophores,” explains João Azevedo, first author of the study. The team used Fluorescence Lifetime Imaging Microscopy (FLIM), a technique that measures the time fluorescence lasts, to achieve this high-resolution sensing. Unlike traditional fluorescence intensity methods, FLIM is less affected by photobleaching, a process where fluorescent markers lose their ability to emit light after prolonged exposure. By focusing on lifetime […]
