Exploiting cyanine dye J-aggregates/monomer equilibrium in hydrophobic protein pockets for efficient multi-step phototherapy: an innovative concept for smart nanotheranostics

Abstract: After several decades of development in the field of near-infrared (NIR) dyes for photothermal therapy (PTT), indocyanine green (ICG) still remains the only FDA-approved NIR contrast agent. However, upon NIR...

“…Taking advantage of radiated and phototriggered modalities, such as deep diagnosis, large imaging area, high accuracy, and spatiotemporal sensitivity, it is possible to design a NG platform with superior precision and efficiency for tumor theranostic. For instance, Cuggino, Calder on et al have recently developed a dual-modal imaging-guided photothermal nanoplatform combining MRI and NIR-induced FLI (Picchio et al, 2021). In this system, casein micelles were prepared using gadopentetic acid as the cross-linker and MRI CA, while ICG J-aggregates were stabilized into the hydrophobic pockets of the protein for efficient PTT and FLI.…”

“…PB-BSA-ICG could provide bimodal FI/MRI of the tumor as well as a combined PTT-PDT ( Sahu et al, 2016 ). The other T 1 -weighted dual-modal nanoprobes were based on Gd or Mn which depended on platforms including serum albumin, regenerated silk fibroin, micelle, monolayered-double-hydroxide nanosheets, carbon cage, and mesoporous silica ( Picchio et al, 2021 ). Among them, taking the most commonly used platform, serum albumin, as an example, the group of Hao integrated ICG and PTX into the albumin corona of Gd 2 O 3 @HSA nanoparticles to prepare PIGH NPs.…”

“…Maziukiewicz et al (2019) mostraram que utilizando um laser de 2 W e ICG em concentrações entre 50 µg/mL e 200 µg/mL, o aumento de temperatura encontrado na amostra foi em torno de 50 °C. (124) Picchio et al (2021) mostraramque, apesar da ICG e os agregados-J da ICG produzirem uma quantidade similar de calor, com um laser de 500 mW e comprimento de onda de 780 nm, os agregados-J da ICG se mostram capazes de produzir calor por mais tempo, sendo mais fotoestáveis (121).…”
