Uglerod nuqtalari (Carbon Dots, CD) ekologik toza va ko ‘p funksiyali nanomateriallar sifatida e’tiborni tortmoqda. Ushbu maqolada tarvuz po ‘ stlog ‘idan foydalanib uglerod nuqtalarining sintezi, o ‘lchamlari va xossalari o ‘ rganildi. Suv, etanol va metanol kabi uch xil erituvchilarda sintez qilingan uglerod nuqtalarining o ‘lchami mos ravishda 76 nm, 48 nm va 7 nm ekanligi aniqlandi. Uglerod nuqtalarining antibakterial va antiviral xossalari mavjud bo ‘lib, ularning strukturasi kristallik ekanligi qayd etildi. Ushbu materiallar tibbiyot, ekologiya va boshqa sohalarda yangi imkoniyatlar yaratadi

Углеродные точки (Carbon Dots, CD) привлекают внимание как экологически чистые и многофункциональные наноматериалы. В этой статье изучается синтез, размер и свойства углеродных точек, полученных из кожуры арбуза. Было установлено, что размер углеродных точек, синтезированных в трех различных растворителях: воде, этаноле и метаноле, составляет соответственно 76 нм, 48 нм и 7 нм. Углеродные точки продемонстрировали антибактериальные и противовирусные свойства, а их структура оказалась кристаллической. Эти материалы открывают новые возможности в медицине, экологии и других областях.

Carbon dots (CDs) are gaining attention as eco-friendly and multifunctional nanomaterials. This paper investigates the synthesis, size, and properties of carbon dots derived from watermelon rind. The size of the carbon dots synthesized in three different solvents, water, ethanol, and methanol, was found to be 76 nm, 48 nm, and 7 nm, respectively. The carbon dots exhibited antibacterial and antiviral properties, and their structure was found to be crystalline. These materials offer new opportunities in medicine, environmental science, and other fields.
