In this study, ultrasensitive and precise detection of a representative brain hormone, dopamine (DA), was demonstrated using functional conducting polymer nanotubes modified with aptamers. A high-performance aptasensor was composed of interdigitated microelectrodes (IMEs), carboxylated polypyrrole nanotubes (CPNTs) and DA-specific aptamers.

Accurate diagnosis of tumor is promising to guide photothermal therapy (PTT) for efficacious tumor ablation with minimal damage to healthy tissues. Here, we report an activatable dual-modal imaging agent, which is based on PEGylated-gadolinium metallofullerene-polypyrrole nanoparticle (PEG-GMF-PPy NP) for imaging-guided
