Characterization of Artificial Chloroplasts

Chloroplasts are important sites for photosynthesis in plants, with excellent structural and functional properties, high light capture efficiency and energy conversion efficiency. The highest energy conversion efficiency of green plants can reach 33%. Artificial photochloroplasts simulate the structure and function of chloroplasts and function by reproducing the natural photosynthesis process. Titanium dioxide is an anatase polycrystal. It was found that the porous nano-layered structure of primitive chloroplasts existed in the titanium dioxide samples. In addition, the presence of gold nanoparticles and nanolayered structure can enhance the photocatalytic performance of TiO₂. This material became a common choice for the preparation of artificial chloroplasts. This artificial chloroplast is simple to prepare, has the characteristics of more stability and longer life, and is deeply loved by researchers.

Services

Over the years, the team at Lifeasible has accumulated rich experience in chloroplast genetic engineering and established a mature artificial chloroplast assembly platform. We can provide artificial chloroplast characterization services while designing artificial chloroplasts based on inorganic semiconductor materials. Our engineers can achieve a variety of methods to improve the photocatalytic performance of TiO₂, including preparation of nanostructured TiO₂, loading of noble metal particles, metal ion doping, dye sensitization, etc. In addition, we adopted various methods to analyze the composition, morphology, optical properties, photocatalytic properties of artificial chloroplasts.

This artificial chloroplast has the structure and function of a complete natural chloroplast. Our engineers have established a set of simple and feasible solutions to provide you with professional and reliable results.

(1) Chloroplasts were extracted from fresh spinach and the integrity of the envelope was detected.
(2) The morphology and function of isolated chloroplasts were characterized by optical microscopy, fluorescence microscopy and transmission electron microscopy.
(3) Using the isolated chloroplast as a template, TiO₂ with the original chloroplast nanolayer sheet structure was synthesized by impregnation, drying and sintering of the precursor.
(4) The microscopic morphology and structure of artificial chloroplasts were analyzed using transmission electron microscopy (TEM) and field emission scanning electron microscopy (FESEM).
(5) For artificial chloroplasts, X-ray diffraction (XRD) was used to analyze the phase structure of the samples.
(6) For artificial chloroplasts, the nano-pore size distribution of the samples was analyzed using the nitrogen adsorption method.
(7) For artificial chloroplasts, the light absorption properties were analyzed using ultraviolet-visible absorption spectroscopy (UV-vis).
