• Synthetic Biology

Background:

• Biological molecules in diagnostic tests face limitations compared to synthetic alternatives.
• Synthetic molecules, particularly peptides, offer advantageous properties for diagnostic applications.
• The field is moving towards replacing biological components with synthetic ones.

Purpose of the Study:

• To review the increasing replacement of biological molecules with synthetic counterparts in diagnostic tests.
• To highlight the advancements in using synthetic peptides and related molecules.
• To discuss the potential for fully synthetic diagnostic assays.

Main Methods:

• Review of current literature on synthetic molecules in diagnostics.
• Analysis of the progression of synthetic peptide use in place of biological antigens.
• Examination of studies on site-specific antibodies induced by synthetic peptides.
• Exploration of emerging research on synthetic antibodies.

Main Results:

• Synthetic peptides are currently the most advanced replacement for biological antigens.
• Synthetic peptides are effectively used to induce site-specific antibodies.
• Emerging evidence suggests synthetic molecules can also replace antibodies.
• The development of diagnostic assays composed entirely of synthetic molecules is becoming feasible.

Conclusions:

• Synthetic molecules offer superior properties for diagnostic applications.
• The transition towards synthetic diagnostic assays is well underway.
• Future diagnostic tests are expected to be built exclusively from synthetic molecules.
