2 . A composition comprising: (i) at least one proteinoid compound comprising a polymeric backbone, wherein said polymeric backbone comprises monomeric units, each of said monomeric units being derived from an amino acid, and wherein said polymeric backbone is characterized by a molecular weight (Mw) of at least 5,000 Da, and (ii) wherein any one of:
at least one proteinoid compound further encapsulates or is attached to at least one antifogging agents; the composition further comprises a substrate having incorporated in and/or on a portion thereof at least one proteinoid compound, optionally wherein the proteinoid compound encapsulates or is attached to at least one antifogging agent; and the composition further comprises a crosslinker, and wherein the proteinoid compound comprises at least one activated double bond, at least one primary amine, or a combination thereof.

3 . (canceled)

4 . The composition of claim 2 , wherein the composition comprises a crosslinker selected from: (i) a crosslinker comprising an acrylate polymer (ii) an acrylate polymer having an average molecular weight in the range of 200 Da to 1000 Da; (iii) a crosslinker comprising a diacrylate monomer, triacrvlate monomer or a combination thereof.

5 . (canceled)

6 . (canceled)

7 . The composition of claim 2 , wherein the composition comprises a crosslinker and further comprising a photo-initiator.

8 . The composition of claim 2 , wherein said amino acid is, in each instance, selected from the group consisting of: Glu, Lys, Asp, Arg, Tyr, His, Ala, Ser, Trp and Phe, Ile, and p-amino benzoic acid.

9 . The composition of claim 2 , wherein said polymeric backbone comprises Glu or Lys.

10 . The composition of claim 9 , wherein said polymeric backbone further comprises Phe.

11 . The composition of claim 9 , wherein said polymeric backbone further comprises Glu or Lys, and Phe and/or Ile.

12 . The composition of claim 9 , wherein said Glu or Lys is at least 20%, by weight, of said polymeric backbone.

13 . The composition of claim 2 , wherein said at least one proteinoid compound is in form of a particle.

14 . The composition of claim 2 , comprising a plurality of said proteinoid compounds.

15 . The composition of claim 14 , wherein at least 80% of the plurality of said proteinoid compounds are characterized by a dispersity index (D) value of less than 1.5.

16 . (canceled)

17 . The composition of claim 2 , wherein said at least one antifogging agent is selected from the group consisting of: sorbitan monooleate (SMO), glycerol monooleate (GMO), glyceryl monostearate, sorbitan monolaurate, sorbitan monostearate, sorbitan trioleate, sorbitan polyethylene oxide, sorbitan monopalmitate, polyoxyethylene sorbitan monolaurate, fatty acid ester of sucrose and any combination thereof.

18 .
