Quantum Dots as Multimodal Photoacoustic and Photothermal Contrast Agents [PDF]

Nano Letters, 2008
Quantum dots (QDs) have primarily been developed as fluorescent probes with unique optical properties. We herein demonstrate an extension of these QD utilities to photoacoustic (PA) and photothermal (PT) microscopy, using a nanosecond pulse laser excitation (420-900 nm, 8 ns, 10(-3)-10 J/cm(2)).

Light-Programmable Morphology in Photothermal Polyurethanes Based on Stenhouse Salt as Photothermal Agent

Journal of the American Chemical Society
Spatially controlled photothermal heating has enabled multiple advances in soft robotics, adaptive structures, and information encoding, but most implementations require multistep processing to localize photothermal additives. Here we report semicrystalline thermoplastic polyurethanes with backbone-integrated Stenhouse salt chromophores that enable ...

Iron Oxide Nanoparticles in Photothermal Therapy

Molecules, 2018
Photothermal therapy is a kind of therapy based on increasing the temperature of tumoral cells above 42 °C. To this aim, cells must be illuminated with a laser, and the energy of the radiation is transformed in heat.
