Full textThe aim of biomaterials design is to create an artificial environment that mimics the in vivo extracellular matrix for optimized cell interactions. A precise synergy between the scaffolding material, bioactivity, and cell type must be maintained in an effective biomaterial. In this work, we present a technique of nanofabrication that creates chemically nanopatterned bioactive silicon surfaces for cell studies. Using nanoimprint lithography, RGD and mimetic BMP-2 peptides were covalently grafted onto silicon as nanodots of various dimensions, resulting in a nanodistribution of bioactivity. To study the effects of spatially distributed bioactivity on cell behavior, mesenchymal stem cells (MSCs) were cultured on these chemically modified surfaces, and their adhesion and differentiation were studied. MSCs are used in regenerative medicine due to their multipotent properties, and well-controlled biomaterial surface chemistries can be used to influence their fate. We observe that peptide nanodots induce differences in MSC behavior in terms of cytoskeletal organization, actin stress fiber arrangement, focal adhesion (FA) maturation, and MSC commitment in comparison with homogeneous control surfaces. In particular, FA area, distribution, and conformation were highly affected by the presence of peptide nanopatterns. Additionally, RGD and mimetic BMP-2 peptides influenced cellular behavior through different mechanisms that resulted in changes in cell spreading and FA maturation. These findings have remarkable implications that contribute to the understanding of cell-extracellular matrix interactions for clinical biomaterials applications

A Step-and-Align Interference Lithography (SAIL) system is developed for fabricating continuous submicron periodic patterns over a silicon wafer with diameter of 100 mm and a metal roller with radius of curvature 25 mm. By utilizing two-beam interference lithography to expose submicron periodic patterns in a small square area and the position stages with high precision control system to stepwise move or rotate the substrate, the small exposure regions are stitched to be large-area submicron periodic patterns. The SAIL system is composed of two fabrication modes; plane mode and roller mode, which can be used to fabricate and stitch the interference patterns on a planar sub-strate and a roller, respectively. A flip bending mirror is used to control the propagation direction of laser beam, and then the interference patterns exposed in the plane or roller mode can be switched conveniently. The optical module in each mode has three functions; beam stabilization function to trace and stabilize the laser beam’s drifting from the argon ion laser placed on a separate table, beam expansion function to expand a small laser beam to a large-area collimated Gaussian beam, and two-beam interference function to have two beams interfered with equal intensity by splitting the expanded beam via a beamsplitter on the substrate coated with photoresist. To obtain uniform exposure dose distribution over the whole large area after step-wise stitching the small exposure regions, a beam profile is designed to have the unit ex-posure area with designed dose distribution. However, there is no beam shaper to trans-form the laser beam into the designed beam. A metal mask with a square open window set up before the substrate is used to truncate the central region of the expanded Gaussian beam whose intensity distribution is more uniform to be the unit exposure area. The Gaussian intensity distribution is smoother in the small region of the expanded beam, which has large tolerance for the overlapping misalignment of two incident beams. Even though the overlapping misalignment is about 2 mm, the interference contrast in the overlapping area could still be higher than 0.99. The interference patterns with period about 700 nm and 800 nm are stitched suc-cessfully over the wafer and the roller. There are about 90 unit exposure areas stitched over the wafer and 120 unit exposure areas stitched over the roller, which take half an hour and an hour, respectively. The process times are much shorter than those of other fabrication methods for making submicron periodic patterns such as e-beam lithography. Although the reflectance spectra of the fringes in the single interference regions and the overlapping regions vary owing to some disturbances, the connection of the submicron periodic fringes and the continuity of fringes for a long distance are verified by utilizing the OM and the SEM. The one- and two-dimensional patterns with the period smaller than 300 nm can be fabricated in the single interference regions without stitching by uti-lizing the optical interference lithography module.
