Abstract: A system, multifunctional chip, and fabrication method thereof are provided. For example, a method for use in fabricating an opto-electromechanical system includes generating, from a film of a material and a substrate on which the film is disposed, a suspended portion of the film by removing a first portion of the substrate such that the film's first portion becomes the suspended portion and a second portion of the film is adjacent to a second portion of the substrate after removing the substrate's first portion. A two-dimensional nanomaterial is thereafter transferred onto a section of the suspended portion of the film via an all-dry process. A cantilever is thereafter generated from the film's suspended portion and extends from the film's second portion. The two-dimensional nanomaterial is disposed on the cantilever. Other aspects and features are also claimed and described.

Abstract: Fabrication methods are provided for transforming two-dimensional films into three-dimensional structures based on rolling-up kirigami techniques. In an example, a method includes forming a first layer of a first material on a portion of a substrate, forming a second layer of a second material on the first layer and a second portion of the substrate, and forming a third layer of a third material on a first portion of the second layer. A pattern is formed into the third layer when forming the third layer. The example method further includes transforming at least a portion of the third layer into a three-dimensional structure based in part on removing a second portion of the second layer and at least a portion of the first layer.

Abstract: A nano scale robotic system for single cell DNA sequencing of a strand of DNA positioned on a slide utilizes an atomic force microscope (AFM) having an end effector in the form of a cantilever with a tip. The AFM causes its cantilever tip to scan over the base pairs of the DNA strand. A pair of spaced-apart electrodes at the tip makes contact with opposite sides of the DNA strand and the current between bases of the DNA strand is measured by a current measurement system connected to the electrodes. An artificial intelligence-based data analytic system determines the DNA sequence based on the current from the current measuring system. The AFM tip is guided over the DNA strand by comparing compressed desired intensity local scan images and compressed actual intensity local scan images and using the difference to control the location of the tip.
