Boron Difluoride Formazanate Dye With Donor Planarization Engineering for 1060 nm Laser Activated Photothermal Theranostics

Advanced Science, EarlyView.
The donor engineering strategy enhances the planarity of the π‐conjugated molecular framework, thereby promoting stronger intramolecular charge transfer (ICT). This structural refinement in FBDFDPA leads to a pronounced bathochromic shift in absorption from the NIR‐I to the NIR‐II region, enabling effective photothermal therapy (PTT) for tumors within ...

A Herbal‐Piezoelectric Heterojunction Strategy to Potentiate Bacterial Cuproptosis‐Like Death and Remodel the Inflammatory Microenvironment in Infection‐Associated Implant Osteomyelitis

Advanced Science, EarlyView.
A titanium implant coating integrating berberine and copper‐doped strontium titanate leverages ultrasound to compromise bacterial membranes and induce cuproptosis‐like death. This approach resolves S. aureus infections in osteomyelitis models while suppressing inflammation and promoting osseointegration, demonstrating a dual‐functional strategy against

Photoacoustic and Photothermal Effects in Particulate Suspensions [PDF]

, 2009
A summary of the research areas investigated by the author during the grant period is given. Experiments and theory have been carried out on the photoacoustic effect arising from a number of physical and chemical processes. A number of studies of the photoacoustic effect as it occurs in transient grating experiments have been completed.

Senescence‐Inducing Therapy Sequential NIR‐II Mild Photothermal/Senolytic Therapy of Triple Negative Breast Cancer

Advanced Science, EarlyView.
Targeting triple‐negative breast cancer remains challenging due to limited therapies and drug resistance. A sequential theranostic strategy combining palbociclib‐induced senescence (enhancing heat sensitivity via HSP70 downregulation) with an NIR‐II nanoplatform (IQ NPs) for mild photothermal therapy (PTT) and quercetin‐mediated senolysis is developed.
