Optical micrograph of Au tubes with micro-diameter and multiple walls that were very extended in length and hence entangled with each other. Such tubular materials were developed from the lamellar condensates fabricated by PLA in water followed by aqueous aging at room temperature for up to 40 days in our interrelated study [10]
