The chosen dye for this work was 5-Chloro-2-[3-[5-chloro-3-(4-sulfobutyl)-3H-benzothi-azol-2-ylidene]-propenyl]-3-(4-sulfobutyl)-benzothiazol-3-ium hydroxide, inner salt, triethylammonium salt (S2275 dye) and was purchased from FEW Chemicals (Wolfen, Sachsen-Anhalt, Germany). To form the J-aggregates, we used sodium chloride (NaCl) from Sigma Aldrich (St. Louis, MO, USA). For the particle stabilization, we used cetyltrimethylammonium bromide (CTAB), (11-Mercaptoundecyl)trimethyl-ammonium bromide (TMA), and poly(diallyldimethylammonium chloride) (PDDA) that were purchased from Sigma Aldrich and 11-Mercaptoundecane-1-sulfonic acid sodium salt (MUS) that was purchased from Prochimia (Gdynia, Poland). Borosilicate cover glass (thickness 0.13–0.16 mm) was used to prepare solid-state samples and was purchased from VWR International (Radnor, PA, USA).

Sodium citrate tribasic dihydrate (ACS reagent, ≥99.0%), cetyltrimethylammonium bromide (CTAB, 99%), sodium borohydride (NaBH4, 99%), L-ascorbic acid (AA, >99%), silver nitrate (AgNO3, >99%), cysteamine hydrochloride (>99%), (11-Mercaptoundecyl)trimethylammonium bromide (TMA, >99%), hydrochloric acid (37%) and tetrachloroauric acid trihydrate (99.9%) were obtained from Sigma-Aldrich. Thiolfunctionalized methoxy-polyethylene glycol (mPEG-SH; MW=5000 Da) was supplied by RappPolymere GmbH. All chemicals were used as received. For all experiments, ultrapure water with a resistivity of 18.2 MΩ•cm was used. Spherical gold nanoparticles with a diameter of 19 nm were prepared using the traditional Turkevich method. 22 These particles were also used for the preparation of larger, 40 nm diameter particles by using modified seeded three-step growth method. 23 The nanorod samples (54x15 nm; 60x16 nm; 80x21 nm) were prepared according to previously published seedmediated protocol.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
