The study published on Monday in the journal Proceedings of the National Academy of Sciences reported that 13 of the 15 prostate cancer patients treated with the photothermal
cancer therapy showed no detectable signs of cancer a year after treatment.
Temporary shapes obtained through combined magnetic actuation and photothermal
heating can be locked by switching off the light and magnetic field.
Polypyrrole is a material known for its photothermal
properties, meaning it's particularly good at converting solar light into thermal heat.
In a photothermal
process, these lasers use a tightly focused beam to deliver intense heat in a highly localised manner, raising the material temperature to induce a change, such as a colour change or an engraving on the surface.

The Mirage IR Microscope operates via the direct detection of the photothermal
infrared (PTIR) response of a sample to exciting IR radiation.
Beale explained: 'Photothermal
therapy involves the use of near infrared laser light to generate localised heating in cancer tumour cells, sufficient to kill them by rupturing the cell membrane or denaturing proteins.
In the US, Sebacia Microparticles is indicated for use as an accessory to 1064 nm lasers to facilitate photothermal
heating of sebaceous glands for the treatment of mild to moderate inflammatory acne vulgaris.
This study found that near-infrared lasers could generate photothermal
effects and antioxidant activity.
In this relatively new technique, the photothermal
effect is applied to the RPE in a more controlled way compared to conventional laser.
To reduce costs and increase printing speed, a photothermal
sensitizer is often added to the powders.
