Abstract

Highlights: Molecular chirality recognized in pharmacokinetics and pharmacodynamics. Supramolecular polymers (SPs) are excellent systems in biological system assembly. Chiral polymeric materials used in catalysis, sensing, optics, and biomedicine. SPs use in drug delivery, anticancer and cell culture and tissue engineering. SPs used in amyloid aggregation inhibition, and antibacterial capability. Abstract : The handedness of chiral-engineered supraparticles (CE-SPs) influences their interactions with cells and proteins, as evidenced by the increased penetration of breast, cervical, and myeloma cell membranes by d -chirality-coordinated SPs. Quartz crystal dissipation and isothermal titration calorimetry have been used to investigate such chiral-specific interactions. d -SPs are more thermodynamically stable compared with l -SPs in terms of their adhesion. Proteases and other endogenous proteins can be shielded by the opposite chirality of d -SPs, resulting in longer half-lives. Incorporating nanosystems with d -chirality increases uptake by cancer cells and prolongs in vivo stability, demonstrating the importance of chirality in biomaterials. Thus, as we discuss here, chiral nanosystems could enhance drug delivery systems, tumor markers, and biosensors, among other biomaterial-based technologies, by allowing for better control over their features.
