Effects of selectively triggered photothermal particles on shape memory polymer composites: an investigation on structural performance, thermomechanical characteristics and photothermal behaviour

open access: yes, 2019
Light-activated shape memory polymer composites (LASMPCs) have the ability to facilitate breakthrough technological advancements in aerospace and space engineering applications since the shape memory effect can be remotely controlled by a light beam ...

Hyaluronic Acid-Modified Gold-Polydopamine Complex Nanomedicine for Tumor-Targeting Drug Delivery and Chemo-Photothermal-Therapy Synergistic Therapy

open access: yes, 2022
Multifunctional nanomedicines for tumor therapy have received more and more attention. Here, we developed a tumor-targeting and pH/near-infrared (NIR) dual stimulus-responsive nanodrug delivery system (PDA-Au@HA/DOX).

Photothermal Microscopy

open access: yesProcedia Materials Science, 2015
AbstractAn accessory for a commercial optical microscope was implemented to map the thermal diffusivity of the sample with high spatial resolution. The system is based in the photothermal technique recently developed by the group. It consists in the measurement with a probe laser of the surface curvature induced by the heat delivered by a modulated ...

Spatially Decoupling Heating and Evaporation for Convection‐Enhanced 3D Solar Evaporation With Continuous Salt Harvesting

open access: yesAdvanced Functional Materials, EarlyView.
An architecture‐enabled bottom‐heated 3D solar convective evaporator spatially decouples photothermal heating from evaporation, triggering natural convection that intensifies sidewall vapour removal and heat transfer. The system achieves significantly enhanced evaporation rates over 2D and conventional 3D designs while confining salt precipitation to ...

Photothermal‐Activated Antibacterial Amyloid‐Polyphenol‐Iron Hydrogels for Synergistic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
We report a thermally triggered supramolecular hydrogel (LTFe) formed by Fe3+ and tannic acid on lysozyme amyloid fibrils. Fe3+ enables rapid gelation and photothermal transduction with an efficiency of 88.56%. The LTFe hydrogel exhibits excellent biocompatibility, potent antibacterial activity against E. coli and S.

Explosive formation and dynamics of vapor nanobubbles around a continuously heated gold nanosphere

open access: yesNew Journal of Physics, 2015
We form sub-micrometer-sized vapor bubbles around a single laser-heated gold nanoparticle in a liquid and monitor them through optical scattering of a probe laser. Bubble formation is explosive even under continuous-wave heating.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

open access: yesAdvanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.
