Abstract
Bacteria are small but need big efforts to control. The use of antibiotics not only produces superbugs that are increasingly difficult to inactivate, but also raises environmental concerns with the growing consumption. It is now believed that the antibacterial task can count on some physiochemical features of material surfaces, which can be anti-adhesive or bactericidal without releasing toxicants. It is necessary to evaluate to what extent can we rely on the surface design since the actual application scenarios will need the antibacterial performance to be sharp, robust, environmentally friendly, and long-lasting. Herein, we review the recent laboratory advances that have been classified based on the specific surface features, including hydrophobicity, charge potential, micromorphology, stiffness and viscosity, and photoactivity, and the antibacterial mechanisms of each feature are included to provide a basic rationale for future design. The significance of anti-biofilms is also introduced, given the big role of biofilms in bacteria-caused damage. A perspective on the potential wide application of antibacterial surface features as a substitute or supplement to antibiotics is then discussed. Surface design is no doubt a solution worthy to explore, and future success will be a result of further progress in multiple directions, including mechanism study and material preparation.

JOURNAL OF MATERIALS SCIENCE. MATERIALS IN MEDICINE 2018; 29:114. [PMID: 30019119 DOI: 10.1007/s10856-018-6120-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/17/2018] [Accepted: 07/04/2018] [Indexed: 06/08/2023]
Abstract
Peptide nucleic acid (PNA) holds enormous potentials as antisense/antigenic drug due to its specific binding ability and biostability with DNA or RNA. However, the poor cellular delivery is the key obstacle in development of PNA therapy. To overcome this difficulty, we developed self-assembled nanoparticles (NPs) for delivery of PNA to living cells using amphiphilic CS derivatives. A series of N,N,N-trimethyl-O-alkyl chitosans (TMACs) with different lengths of alkyl chains were synthesized. The structures of these synthesized chemicals were characterized with FT-IR and 1H NMR. We found that the TMACs were all able to self-assemble in aqueous condition to form nano-size NPs. These nano-size NPs are spherical shape with a size range of around 100 nm and a zeta potential above +30 mV. PNA was easily encapsulated into chitosan derivative NPs by an ultrasonic method with entrapment efficiency up to 75%. The PNA-loaded TMAC NPs released the drug in a sustained manner in PBS (pH 7.4) at 37 °C. N,N,N-trimethyl-O-cetyl chitosan (TMCC) showed the best in vitro hemocompatibility and cell viability. These TMCC based NPs were able to dramatically increase the cellular uptake of PNA, specifically, 66-fold higher compared to without using these nanoparticles. The results suggest that the designed TMCC NPs might be a promising solution for improving cellular delivery of PNA.
