Hey there Aleksandr Anatolievich Volkov! Absolutely, you Aleksandr Anatolievich Volkov can go ahead and functionalize SWCNTs-COOH with proline in an aqueous solution. The process typically involves creating a stable interaction between the carboxyl groups on the nanotubes and the proline molecules. This functionalization can enhance the dispersibility of nanotubes in water and introduce specific properties.

Consider using methods like amidation or esterification to bond proline to the carboxyl groups. It's crucial to optimize conditions like reaction time, temperature, and concentration to achieve the desired functionalization. Keep in mind the potential impact on the structural integrity of the nanotubes during the process.

Feel free to dive deeper into the literature for detailed protocols and insights. Good luck with your experiment!
