Microalgae have long been used for the commercial production of natural colorants such as carotenoids and chlorophyll. Due to rising demand other products from microalgae, strategies increase efficiency are urgently needed. The microalgal biorefineries has limited countries with moderate climates. For cooler climates less daylight, methodologies efficient need be investigated. Algal strains tha...

This research sheds light on the analysis of pigments and adhesives applied a color painting wooden architecture in Taiping Heavenly Kingdom Prince Dai’s mansion, located Changzhou, Jiangsu Province China. Four samples were collected from above building beam analyzed identified using series techniques, including polarized microscopy (PLM), scanning electron microscope coupled with an energy-dis...

Macroalgae or also known as seaweed is a low-level plant that does not have true roots, stems and leaves. The function of the leaves replaced by thallus. purpose this study was to composition macroalgae pigments (Gelidium corneum) originating from Yakoba Beach, Jayapura City. method used in research an experimental with pigment analysis using Thin Chromatography Visible UV Spectrophotometry. TL...

The possibility of stabilizing emulsions of water and non-polar alkane with pure, coloured organic pigment particles is explored. Seven pigment types each possessing a primary colour of the rainbow were selected. Their solubility in water or heptane was determined using a spectrophotometric method and their surface energies were derived from the contact angles of probe liquids on compressed dis...

AIMS To report the optical coherence tomographic (OCT) findings in retinal pigment epithelium (RPE) detachments. METHODS 24 eyes were analysed by OCT and by fluorescein (FAG) and/or indocyanine green angiography. RESULTS RPE detachments were classified by the OCT images into those with a partial or total highly reflective line in the area of the detachment (nine eyes), and those that showed...

OBJECTIVE To evaluate the potential cytotoxic effects of indocyanine green (ICG) on cultured human retinal pigment epithelium (RPE) and the resultant implications for macular hole surgery. METHODS Human RPE cells were exposed to ICG in concentrations from 0.001 to 5 mg/mL. The exposure duration ranged from 5 minutes to 3 hours. Light microscopy, MTS viability assay, and calcein AM-ethidium ho...

ABSTRAK Klorofil merupakan pigmen berwarna hijau yang terdapat pada tumbuhan atau daun hijau. Pigmen klorofil berfungsi menyerap energi cahaya dan mengkonversi tersebut menjadi kimia. Selain itu, juga dapat mentransfer elektron, sehingga ini digunakan sebagai fotosensitizer alami perangkat sel surya tersensitisasi dye (DSSC). Fotosensitizer memiliki beberapa kelebihan seperti harganya murah, ju...
