RESUMO
La rinosinusitis (RS) se define como la inflamación de la nariz y los senos paranasales con dos o más síntomas como bloqueo/obstrucción/congestión o secreción nasal (goteo nasal anterior/posterior) más dolor/presión facial y/o reducción o pérdida del sentido del olfato. Adicional, se tienen en cuenta los hallazgos objetivos como la presencia de pólipos nasales y/o descarga mucopurulenta en meato medio y/o edema u obstrucción de la mucosa en el meato medio en la endoscopia nasal. Se pueden considerar o no, los cambios tomográficos como cambios mucosos en el complejo osteomeatal y la mucosa de los senos paranasales. Se reconoce que los síntomas tienen alta sensibilidad, pero baja especificidad, de ahí la necesidad de hallazgos objetivos.

In addition, objective findings such as the presence of nasal polyps and/or nasal presence of nasal polyps and/or mucopurulent discharge from the middle meatus and/or edema or mucosal obstruction or mucosal obstruction in the middle meatus on nasal endoscopy. Tomographic changes may or may not tomographic changes may or may not be considered as mucosal changes in the osteomeatal complex and mucosal osteomeatal complex and the mucosa of the paranasal sinuses. It is recognized that the symptoms symptoms have high sensitivity but low specificity, hence the need for objective findings. findings.

A holistic approach to fabricate a hierarchical electrode that consists of redox-active poly(1,5-diaminonaphthalene), 1,5 PDAN, uniformly and conformally grafted onto a 3D carbon nanotube (CNT-a-CC) electrode is set forth. The CNT-a-CC electrode was formed by direct growth of high-density CNTs on the surface of every individual microfiber, the constituent of activated carbon cloth (a-CC). Owing to the naphthalene backbone, conformal deposition of 1,5 PDAN on carbon surfaces has been readily attained via electropolymerization. This hierarchical platform with open and continuous nanochannels formed by CNTs coupled with excellent electrical connectivity between CNTs and the polymer provides a reproducible platform for electrochemical investigation. According to multiple sample analyses on CNT-a-CC, the gravimetric capacitance of 1,5 PDAN is up to 1250 F/g, and this value can be maintained up to 100 mV/s. Hierarchical organization provides a specific capacitance of 650 F/g at 2 mV/s at a 1,5 PDAN loading of 2.5 mg/cm2. The conjugated ladder structure of the polymer led to strong π-π interactions between the polymer and CNT-a-CC together with mechanically robust CNT-a-CC. A capacitance retention of 94% for 1,5 PDAN has been obtained after 25,000 cycles at 100 mV/s, a significant cycle stability improvement over conventional conductive polymers such as polyaniline. This new lightweight electrode that seamlessly integrates functional species with nanochannel-like CNT-a-CC opens up a new opportunity to harness electrochemical reactions in the 3D carbon electrode for energy storage and electrocatalysis as well as electrochemical sensing.
