Question

Difference between acid terminated and ester terminated plga

Answer 1

The ester terminated plga will be more hydrophobic than the acid terminated, thus you can expect more attraction between plga molecules than with water, this could end up in larger nanoparticles.

acid terminated==In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation into proteins. Proteins are based on polypeptides, which are unique sequences of amino acids.

terminated plga==LGA is available with different end groups, namely a free carboxylic end group and an ester-terminated group.7 End-capped PLGA usually has a lauryl or a methyl ester, and is more stable than uncapped PLGA
