Two Photon Polymerization

Organic-modified ceramics (Ormocer) are an outstanding class of hybrid materials due to the fact of their various excellent properties, and they have been successfully used in two-photon polymerization microfabrication fields. A series of functional devices has been fabricated and widely used in aerospace, information science, biomedicine, and other fields. However, quantization of intermolecular energy during the fabrication process is still a difficult problem. A stochastic multi-molecular modeling method is proposed in this paper. The detailed molecular-interaction energies during the photon polymerization of Ormocer were obtained by molecular dynamics analysis. The established molecular model was verified by comparing the simulated shrinkage results with commercial calibrated ones. This work is expected to provide a reference for optimizing the fabrication of organically modified ceramics and reducing photoresist shrinkage in two-photon polymerization.

Two Photon Polymerization

Organically modified ceramics are used as photoresistors in the present work. The role of every ingredient played in two photon polymerization process is analyzed. A simple, compact and easy to locate experimental scheme is designed to fabricate nanorods in Ormocer. Based on the threshold theory of photon intensity, the lateral size dependences and vertical size dependences of nanorods on laser power and scanning speed are investigated, respectively. Through systematically changing processing parameters, a 136[Formula: see text]nm Ormocer suspended nanorod which is beyond diffraction limit resolution is obtained when [Formula: see text]m/s, [Formula: see text][Formula: see text]mW. By this means, two photon polymerization techniques show great potential to obtain a limiting resolution of Ormocer. What is more, micro gear, micro chair, photonic crystal and micro annular lens are fabricated in two photon polymerization in order to exhibit excellent mechanical and optical property of Ormocer.

AbstractOver the past twenty years, the use of rapid prototyping techniques for processing of medical devices has seen rapid growth. A number of rapid prototyping techniques currently exist for producing a broad range of medical devices using metals, ceramics, polymers, and composite materials. One promising rapid prototyping technology for creating medical devices with small scale features is two photon polymerization; this scalable photopolymerization technique enables processing of photosensitive materials such as organically-modified ceramic materials. In this study, two photon polymerization was used to produce microneedles that mimic the anatomy of the mosquito fascicle. The labrum of the mosquito was replicated in the mosquito-like microneedle. On the other hand, the maxillae of the mosquito were not replicated in the mosquito-like microneedle; the absence of these features was attributed to inadequate mechanical support of the maxillae. This study suggests that two photon polymerization and other rapid prototyping technologies may be used to produce biomimetic drug delivery devices that imitate the intricate structures found in nature.
