Peptide nucleic acids, is an analogue of oligonucleotide in which sugar-phosphate backbone has been replaced by a polyamide chain. Due to the unique backbone of PNA, it can be used in same applications as conventional DNA/RNA.

Proteins, (for example, collagen) are comprised of amino acids and orchestrated in a long chain-like Configuration. This chain of amino acids is comprised of peptides. The chain is then separated into littler chains, which can infiltrate the top layer.

Antimicrobial peptides (AMPs), also called host defense peptides (HDPs), which commonly content 5-40 amino acids, are natural antibiotics produced by various organisms. The first AMP was found by Dubos when extracted an antimicrobial agent from a soi

pH-sensitive linkers (acid-labile linkers), are a class of chemically cleavable linkers that were first used in early ADC developments. Hydrazonesand cis-Aconityl is among the most widely used pH-sensitive linkers. A cis-aconityl linkage is offen use
