1. What is Two-Photon Direct Laser Writing (DLW)? Two-photon direct laser writing (DLW) is 3D printing for the microscopic world. This techniques
Two-photon absorption (TPA) is the simultaneous absorption of two-photons of the same or different wavelenth by a material. In physics two-photon absorption
Researcher’s led by Prof. Hongbo Sun at Tsinhua university, Beijing has put the protein bovine serum albumin (BSA) to use as a muscle in microstructures. Microstructures fabricated by two-photon laser direct writing
This post deals with the a new method for mulimaterials two-photon lithography from the paper entitled “Multimaterial 3D laser microprinting using an integrated microfluidic system” published in Science Advances[1] . Facile integration of
Commercial direct laser writing systems are relatively new with the first firms offering such products emerging around 2007. The following is a short list of companies offering such products. There are broadly
Dip-in two-photon lithography (DTPL) system was developed to overcome some limitations of the conventional TPL system (Figure 1). In dip-in two-photon lithography the lens is in direct contact with (dipped into) the
This video demonstration of two-photon lithography (laser direct writing) shows the fabrication of a microscopic castle on top a pencil lead. It was produced and shared by the team led by Prof.
Current techniques provide 3D printing of structures as small as few nanometers. Main candidates from producing complex 3D structures are two-photon lithography, ion-beam lithography and Atomic force microscopy based lithographic technique. The
This post will introduce a roll call of classic papers about direct laser writing (DLW) in a chornological order, and talk briefly about their significance. Over the years there have been many
1. What is Two-Photon Direct Laser Writing (DLW)? Two-photon direct laser writing (DLW) is 3D printing for the microscopic world. This techniques goes beyond the smallest shapes and sizes that can be
Two-photon absorption (TPA) is the simultaneous absorption of two-photons of the same or different wavelenth by a material. In physics two-photon absorption is categorized as a third-order nonlinear optical phenomenon. The image on
