1. A method of making camel hair derived-polypeptide conjugated carbon quantum dots (CH-CQDs)-metal hybrid nanoarchitectures, the method comprising:
making the camel hair derived-polypeptide conjugated carbon quantum dots (CH-CQDs) by
obtaining camel hair,
mixing the camel hair with water to obtain a mixture,
heating the mixture to obtain a heated mixture,
cooling the heated mixture to obtain a cooled mixture,
centrifuging the cooled mixture to obtain camel hair derived-polypeptide conjugated carbon quantum dots (CH-CQDs), and
filtering the camel hair derived-polypeptide conjugated carbon quantum dots (CH-CQDs) from the cooled mixture;
preparing the camel hair derived-polypeptide conjugated carbon quantum dots (CH-CQDs) in liquid form to obtain a plurality of camel hair derived-polypeptide conjugated carbon quantum dots (CH-CQDs) solutions;
preparing a plurality of metal precursor solutions;
individually adding one of each of the plurality of metal precursor solutions to one of each of the plurality of camel hair derived-polypeptide conjugated carbon quantum dots (CH-CQDs) solutions to obtain a plurality of resultant mixtures; and
individually mixing each of the plurality of resultant mixtures to obtain a plurality of camel hair derived-polypeptide conjugated carbon quantum dots (CH-CQDs)-metal hybrid nanoarchitectures.
