Water peel-off transfer of electronically enhanced, paper-based laser-induced g...
Pinheiro, Tomás; Correia, Ricardo; Morais, Maria; Coelho, João; Fortunato, Elvira; Sales, M. G. F.; Marques, Ana C.; Martins, RodrigoLaser-induced graphene (LIG) has gained preponderance in recent years, as a very attractive material for the fabrication and patterning of graphitic structures and electrodes, for multiple applications in electronics. Typically, polymeric substrates, such as polyimide, have been used as precursor materials, but other organic, more sustainable, and accessible precursor materials have emerged as viable alternativ...
Laser-induced graphene on paper toward efficient fabrication of flexible, plana...
Pinheiro, Tomás; Silvestre, Sara; Coelho, João; Marques, Ana C.; Martins, Rodrigo; Sales, M. Goreti F.; Fortunato, ElviraAbstract Laser irradiation to induce networks of graphene-based structures toward cost-effective, flexible device fabrication is a highly pursued area, with applications in various polymeric substrates. This work reports the application of this approach toward commonly available, eco-friendly, low-cost substrates, namely, chromatographic and office papers. Through an appropriate chemical treatment with sodium t...
Paper-based biosensors for COVID-19: a review of innovative tools for controlli...
Pinheiro, Tomás; Cardoso, A. Rita; Sousa, Cristina E. A.; Marques, Ana C.; Tavares, Ana P. M.; Matos, Ana Miguel; Cruz, Maria TeresaThe appearance and quick spread of the new severe acute respiratory syndrome coronavirus disease, COVID-19, brought major societal challenges. Importantly, suitable medical diagnosis procedures and smooth clinical management of the disease are an emergent need, which must be anchored on novel diagnostic methods and devices. Novel molecular diagnostic tools relying on nucleic acid amplification testing have emer...
Non-enzymatic lab-on-paper devices for biosensing applications
Marques, Ana Carolina; Pinheiro, Tomás; Martins, Gabriela Vieira; Cardoso, Rita; Martins, Rodrigo; Sales, M. G. F.; Fortunato, ElviraLab-on-paper devices constitute a promising tool for biosensing systems due to their easiness of fabrication and use, inherent low-cost, easy tailoring in terms of device architecture and/or function, biocompatibility and easy disposal. When combined with non-enzymatic approaches the increase on device's shelf life, stability and analytical features improvement can be achieved. In this chapter, a brief descript...
