Te concentration was determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES; PerkinElmer Inc., Waltham, MA, USA) method, as previously described.8 (link) Briefly, the sample was digested with 3 mL concentrated nitric acid and 1 mL H2O2 in a digestive stove (Shanghai Qian Jian Instruments Co, Ltd., Shanghai, People’s Republic of China) at 180°C for 3 hours. Then, the digested product was reconstituted to 10 mL with Milli-Q H2O and used for total Te determination. To determine inorganic Te concentration, the dried algal samples were extracted with 15% HCl; then, the extract was analyzed by ICP-AES directly. Organic Te concentration was calculated as the difference between the total Te concentration and the inorganic Te concentration.

The ICP-AES (Inductively Coupled Plasma Atomic Emission Spectroscopy) is a laboratory instrument used for the detection and quantification of trace elements in various samples. It utilizes a high-temperature plasma to atomize and ionize the sample, and then measures the characteristic emission spectra of the elements present to determine their concentrations.

The degradation behaviour of the hydrogels was evaluated by measuring wet weight of the hydrogels (weight of the water-absorbed gel after the excessive fluid is removed from the gel) over time in phosphate buffered saline (PBS, pH 7.4). Hydrogels (10 mg) were placed in polypropylene conical tubes (Cole-Parmer Instrument Company LTD, Eaton Socon, UK), each containing either 5 mL PBS or 5 mL PBS containing 1.5 mg/mL lysozyme. The PBS solutions were replaced with fresh solutions daily. This ensured active lysozyme was present in the media [70 (link),87 (link)]. The hydrogel sample and solution were sealed and maintained at 37 °C with mild agitation (50 rpm) for the duration of the study. Chitosan-free inorganic hydrogels (GLMS hydrogel) (10 mg) prepared by dissolving 0.1 g GLMS in 1mL water at 10 wt% were used for comparison. Inductively coupled plasma atomic emission spectroscopy (ICP-AES, PerkinElmer, Waltham, MA, USA) was used to obtain the soluble silica release profiles in PBS solution and high-performance liquid chromatography (HPLC, Shimadzu, Wolverton, UK) was used for the quantification of glycerol and glucose in degradation solutions.

To load CisPt and EA, 16 mg of SHMONs were initially dispersed in 8 mL of CisPt solution (0.5 mg/mL in saline) and stirred in the dark for 24 h. Then, the CisPt-loaded nanoparticles (CisPt@SHMONs) were collected by centrifugation and washed to remove free drugs. Next, CisPt@SHMONs were dispersed in 8 mL of EA solution (2 mg/mL in ethanol) and stirred in the dark for another 24 h. Finally, the (CisPt+EA)@SHMONs were obtained after centrifugation and washing. For each drug loading step, the supernatant and washing solution were collected and determined to calculate the drug loading content. The Pt content was quantified by inductively coupled plasma-atomic emission spectrometry (ICP-AES; Optima 8300, PerkinElmer, USA). The EA content was quantified by UV–Vis spectrophotometer. Drug release was detected by dialysis method with TCEP·HCl as the reducing agent. Ten mg of drug-loaded nanoparticles were transferred into a dialysis bag (MWCO 8–14 kDa). The bags were immersed in 30 mL of PBS (pH 7.4) with or without 10 mmol/L of TCEP·HCl, which were incubated in a shaker at 37 °C. At predetermined time points, 20 mL of the release medium was sampled and replaced with equal amount of fresh medium. The Pt content was quantified by ICP-AES (PerkinElmer).

All the reagents supplied by Aladdin were used as received without further purification unless otherwise stated. Equal volumes (1 mL) of organic phase and aqueous phase were stirred for the extraction of Am(lll) and Eu(lll). The extraction of Am from HNO3 solution was performed at 298 ± 0.1 K. Nitric acid solution spiked with 241Am tracer amount was mixed with 0.5 mmol/L BTPhen ligands dissolved in n-octanol by Vortex oscillator for desired time (max. 120 min and min. 5 min). Temperature controlled extraction was carried out in the water bath magnetic stirrer with magneton in the plastic vials to maintain constant temperature during extraction. As for extraction of Eu(lll), it was conducted in the nonradioactive condition. The mixture for both Am and Eu extraction was centrifuged for 5 min to separate phases. The activity of 241Am and amount of Eu were separately determined by Tricarb 2910 tr liquid scintillator (Perkin Elmer company) and inductively coupled plasma atomic emission spectrometer ICP-AES. Distribution ratio of Am is determined by the ratio between the radioactivity counts of organic phase and aqueous phase after extraction. Distribution ratio of Eu(lll) is defined by the concentration of the Eu3+ in the organic phase divided by that in the aqueous phase. The separation factor (SFAm/Eu) was calculated by the ratio of distribution ratios between Am(lll) and Eu(lll).
