Fig 2 - uploaded by Sudipta Mallick. We note that after silica coating the absorption spectra show little difference Fig.
When we checked the temperature increment after silica coating, we observed little difference as compared to bare Au nanorods. This difference in temperature shown in Fig.
Still the resulting temper- ature is high enough to induce cellular hyperthermia with decreased toxicity. However, GNRs are not sufficiently stable for long-term storage 16 and require a protective coating with polymers such as polyelectrolytes, poly- ethylene glycol, polyaniline, and silica   generating nanocomposites A Study of Antibacterial and Redox Activity.
Upon exposure to a laser beam, AuNPs enable to absorb light and to convert it into heat with high efficacy and thus this technique has been employed to locally destroy cancer cells[,].
A and nr bare
Various shapes of AuNPs such nanospheres, nanorods, nanocages[,], nanoshells and caged gold nanorodshave been served on this purpose. However, gold nanostructures with optical properties tunable in the near-infrared region — nm are particularly attractive for cancer therapy.

Recent advances using gold nanoparticles A and nr bare a promising multimodal tool for tissue engineering and regenerative medicine. Combining high yield fabrication with theoretical modeling, size, and shape control of noble metal nanostructures has been greatly advanced in the fields of optoelectronic devices [1, 2], plasmon-enhanced spectroscopy [3, 4]bioimaging, and ther- apeutics [5, 6], and so forth This optical tunability has brought several advantages to Au NRs.
For example, the accessible NIR SPR L extinction is consistent with the transparent window of human tissue facilitating widespread biophotonics applications in bioimaging and NIR photothermal cancer therapy [5, 6, 17].
The SPR L is highly sensitive to medium, surface charge density, aspect ratios, surface coating, and aggregation degree or assembly mode ; therefore, they have promising applications in chemical and biological sensing For bioapplications, Au NRs need to be highly stable, biocompatible, sensitive, and targetable [5, 6, 17, 26].
Monodispersed colloidal Au NRs are often prepared by seed-mediated method in the presence of cationic surfactant CTAB as a " soft template " with continuous optimization Role of surface modification in zinc oxide nanoparticles and its toxicity assessment toward human dermal fibroblast cells.
