Enhancing the detection of Dinophysis spp. using electrochemical genosensors
Pereira, Eduarda; Silva, Aurora; Morais, Stephanie L.; Costa-Rama, Estefanía; Moreira, Patrícia R.; Fraga-Corral, M.; Torrado, Ana M.Background: Harmful algal blooms (HABs) pose a significant threat to the environment and public health. These blooms are defined by an accumulation of microscopic algae in water, and they can occur in lakes, rivers, estuaries, or coastal areas. Factors like the unregulated runoff of agricultural and industrial wastes into the aquatic environment [1] are believed to have transformed these ecosystems into favorab...
Is it possible to prevent Harmful Algal Blooms? An electrochemical genosensor t...
Pereira, Eduarda; Silva, Aurora; Morais, Stephanie L.; Costa-Rama, Estefanía; Moreira, Patrícia R.; Fraga-Corral, M.; Torrado, Ana M.Harmful Algal Blooms (HABs) are a very common phenomenon in the last few years that results from the accumulation of microalgae, such as dinoflagellates of the Dinophysis genus. Hence, the development of analytical technologies capable of detecting these microorganisms and thereby avoiding environmental and public health crisis, has become a major priority. Biosensors have been gaining recognition lately given ...

Screen-Printed Electrode-Based Sensors for Food Spoilage Control: Bacteria and ...
Torre, Ricarda; Costa-Rama, Estefanía; Nouws, Henri P. A.; Delerue-Matos, CristinaFood spoilage is caused by the development of microorganisms, biogenic amines, and other harmful substances, which, when consumed, can lead to different health problems. Foodborne diseases can be avoided by assessing the safety and freshness of food along the production and supply chains. The routine methods for food analysis usually involve long analysis times and complex instrumentation and are performed in c...
Disposable Sensors in Diagnostics, Food, and Environmental Monitoring
Dincer, Can; Bruch, Richard; Costa-Rama, Estefanía; Fernández‐Abedul, Maria Teresa; Merkoçi, Arben; Manz, Andreas; Urban, Gerald Anton; Güder, FiratDisposable sensors are low-cost and easy-to-use sensing devices intended for short-term or rapid single-point measurements. The growing demand for fast, accessible, and reliable information in a vastly connected world makes disposable sensors increasingly important. The areas of application for such devices are numerous, ranging from pharmaceutical, agricultural, environmental, forensic, and food sciences to we...
Label-free Voltammetric Immunosensor for Prostate Specific Antigen Detection
Oliveira, Nélia; Costa-Rama, Estefanía; Viswanathan, Subramanian; Delerue-Matos, Cristina; Pereira, Lourdes; Morais, SimoneThis work describes a sensitive voltammetric immunosensor for label‐free electroanalysis of the prostate specific antigen (PSA), the main biomarker of prostate cancer. A gold electrode was firstly modified with the optimum self‐assembled monolayer (SAM), 1,6‐hexanedithiol, followed by the subsequent adsorption of gold nanoparticles (AuNPs) and, then, the monoclonal antibody to recognize PSA was immobilized. The...
