  1. Great paper, congratulations getting it published!

    Interesting the dynamic shift caused by changes in just the surface structure. Considering the gold nanoparticle constructs heat to around 28-32C (room temp 22C + 6-10C) at the respective wavelengths (532 and 690 nm), do you believe further modifications of the surface structure could reach above 37C to a therapeutic level to treat cancers?

    I am imagine this refinement will benefit future nanoparticle designs and shapes such as the gold nanoparticle rods mentioned in your paper. I presume laser strength is maxed 1 w/cm^2 so a stronger laser cannot be used otherwise damage to healthy cells – https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201900471

    You should write up the summary for interest laymans! I’d be happy to write something if you would like as well.

    Well done!

    • Hi Matthew,

      Great to hear from you and thank you for reading!

      This is a great point about the temperature reached using these nanoparticles. We used very low concentrations of nanoparticles in this work, so increasing this concentration could yield temperatures above the therapeutic requirement. Also, as you say the laser power is quite high – but owing to the magnetic nature of the hybrid nanostructure, magnetic hyperthermia could potentially be used in conjunction with the photothermal conversion.

      I’m currently working on sequels to this paper (and the dreaded thesis!), exploring the magnetic and nonlinear optical properties of the multistaged magnetic-plasmonic nanoparticles. Once published I will definitely write up a layman summary of it all!

      Hope you are keeping safe and enjoying your postdoc at the University of Kent, it has been great reading about your journey 🙂

  2. Ah, that makes a lot of sense. Thanks for taking the time to answer!

    Also apologies for my ignorance, I naively read “…magnetic…” and assumed it was merely a method for only providing specific anatomical location on an In vivo model and ultimately a patient. Magnetic hyperthermia is interesting and something I’ve not heard much about. It’s something to read up on when I have time (so not going to happen anytime soon!). Might be when you write everything up in layman terms 🙂

    I look forward to the sequels to this paper! I know little to nothing about nonlinear optical properties of the multi-staged magnetic-plasmonic nanoparticles but if it is anything like traditionally optical techniques dealing with reconstruction to state of the art manipulation of phase for holographic imaging, perhaps I can understand enough 😀

    Thank you for your kind words! Almost at the end of the post doc at the University of Kent so I am looking for new opportunities in London now. I am looking into the industry sector due to the lack of publications and some of the issues with academia which I have highlighted a little in my blog. It’s been going well considering the current climate of current/post-COVID and WFH.

    Hope you are coping and keeping safe in the this climate too! 🙂
