Glycine (98%), 6-bromohexanoic acid (98%) and 2,3,3-trimethyl-3H indole (98%) were purchased from ACROS (Beijing, People’s Republic of China). Rhodamine123 was purchased from Sigma-Aldrich Co (St Louis, MO, USA). Thin layer chromatography was used to monitor chemical reactions with GF254 silica gel plates. Products were purified with silica gel flash chromatography. Arium pro ultrapure water (18.2 MΩ cm; Sartorius Stedim Biotech GmbH, Goettingen, Germany) was used throughout the analytical experiments.
Arium pro ultrapure water
Manufactured by Sartorius
Sourced in Germany
The Arium pro ultrapure water system is a compact, highly efficient water purification device designed to provide ultrapure water for various laboratory applications. The system utilizes a multi-stage purification process to remove impurities, ensuring the delivery of consistently high-quality ultrapure water.

Approximately 100 mg of each sample was transferred to a 50 mL
centrifuge tube, to which 35 mL of 30%
H2O2 (w/w) (Honeywell Fluka™)
was added in order to remove the organic content. The tubes were sonicated (VWR
ultrasonic cleaner) for 10 min to disaggregate the solids. The samples were
agitated in an orbital shaking incubator operating at 100 rpm at 35 °C. After
72 h, the samples were centrifuged at 4000 rpm for 10 min (Eppendorf centrifuge
5810). The supernatant was removed and replaced with new
H2O2. This was repeated six
times until no more organic oxidation was observed. The mineral fraction was
washed three times in water (Sartorius arium pro ultrapure water) for 24 h, with
centrifugation succeeding each wash. The organic-free mineral fractions were
dried at 35 °C prior to particle size analysis measured by Kerstin Jurkschat
using a DC24000 CPS disc centrifuge65 (link) at Oxford Materials Characterisation
Services, Oxford, UK.

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.
