Today, the use of biomaterials in many biomedical platforms is becoming increasingly popular due to their high diversity, infinite mimicking capacity, and emerging functions. Applications currently cover diverse areas in biomedicine including systems for cell isolation, expansion and maintenance, platforms for drug and cell delivery, scaffolds for tissue engineering, tissue regeneration and repair, cancer therapy, etc. Biomaterials in general can be: (1) natural in origin such as many proteins from the extracellular matrix, natural polysaccharides or scaffolds presented in a blood clot or (2) synthetic, including polymers, ceramics, or peptides. In this review, we focus on the use of self-assembling peptide scaffolds as an innovative and reliable strategy to obtain platforms for cell and drug delivery to injured or diseased tissues and organs. This type of material is molecular by design and it develops spontaneously into nanofiber scaffolds with multiple uses. In particular, examples are given for applications in the area of cardiac repair and regeneration.

Peptides can be designed to self-assemble into predefined supramolecular nanostructures, which are then employed as biomaterials in a range of applications, including tissue engineering, drug delivery, and vaccination. However, current self-assembling peptide (SAP) hydrogels exhibit inadequate self-healing capacities and necessitate the use of sophisticated printing apparatus, rendering them unsuitable for 3D printing under physiological conditions. Here, we report a precisely designed charged peptide, Z5, with the object of investigating the impact of electrostatic interactions on the self-assembly and the rheological properties of the resulting hydrogels.

Host-directed therapies (HDTs) resolve excessive inflammation during tuberculosis (TB) disease, which leads to irreversible lung tissue damage. The peptide-based nanostructures possess intrinsic anti-inflammatory and antioxidant properties among HDTs. Native carnosine, a natural dipeptide with superior self-organization and functionalities, was chosen for nanoformulation.
