Abstract: An isolated or recombinant polypeptide is provided and comprises a sequence selected from the group comprising NI01, ?1?2, ?2?3, ?3?4, ?1?2?3, ?2 ?3 ?4, R-NI01, NT-205, H16, H1M NI01-R, 3NH (?1?3?3), H1 (?1?2), H2 (?2?3), 3HC (?2?3?4) or having at least 75% identity thereto, wherein the isolated or recombinant polypeptide is bactericidal and/or bacteriostatic.

Abstract: A cyclic peptide (10) includes two domains (D1,D2), each including three charged sub-domains (14, 16). The first domain (D1) includes two anionic sub-domains (14) followed by a cationic sub-domain (16). The second domain (D2) includes two cationic sub-domains (16) followed by an anionic sub-domain (14). The two domains are connected to one another and separated by a tri-glycyl linker (12). The cyclic peptide (10) is able to self-assemble into a network able to mimic an extracelluar matrix, and which promotes cell growth while resisting biofilm formation.
