The present disclosure relates to a liver organoid, more specifically, to a liver organoid in which a liver lobule-type structure can be maintained for a long time and a preparation method using the same. The liver organoid of the present disclosure comprises: a tubular outer cavity the inside of which is divided into a plurality of compartments; a cell aggregate loaded into the compartments; and an inner cavity located at the core of the outer cavity.

Provided herein are methods for the preparation of perfusable scaffolds for cell culture. These methods can comprise providing a bioink composition and a fugitive ink composition; chaotic printing the bioink composition and the fugitive ink composition to generate a microstructured precursor comprising a plurality of lamellar structures formed from the bioink composition; curing the bioink composition to form a cured scaffold precursor; and removing the fugitive ink from the cured scaffold precursor, thereby forming the perfusable scaffold. Also provided are scaffolds prepared by these methods as well as modular bioreactors incorporating these scaffolds.

A biodegradable and biocompatible three dimensional construct comprising a combination of a nano silicate (e.g., laponite) and two different polymers, the two polymers each individually providing at least one covalently linked polymer chain and at least one ionically linked polymer chain, the polymeric chains forming a dual strengthening intertwined polymeric system. The constructs demonstrate improved mechanical and strength properties, while the bioinks provide a material having superior printability characteristics suitable for printing a three dimensional biodegradable construct having an aspect ratio of greater than 2.0. The bioink may also comprise cells or combinations of cells. Methods of using the constructs and bioinks for wound healing preparations and tissue regeneration are also provided.

Problem to be solved: To provide a whitened or opacified capsule and film without using a white pigment such as titanium dioxide. Solution: A film, a capsule and a film-forming composition characterized by containing a film-forming polymer component selected from gelatin and pullulan and an opacifying agent consisting of a water-soluble salt except calcium salt carbonate and bicarbonate, wherein the salt is selected from a sodium salt, potassium salt, an ammonium salt and a magnesium salt.

A process for making a conductive ink formulation for jet-printing which uses a fine-tuned molecular weight of hydrolyzed starch particles and using microwave-assisted synthesis to produce a stable, monodisperse, aqueous-based gold ink formulation. This aqueous ink formulation is shown to be highly jettable and forms films which sinter at relatively low temperatures. Printed gold film using the formulation can achieve <1.0 Ω/square sheet resistance upon drying for about 30 minutes and sinters at 200° C. thereby improving its conductivity.
