A composition includes a target pharmaceutical or biological agent, a solution containing the target pharmaceutical or biological agent, and substrate that is soluble in the solution. The substrate is capable of being solidified via a solidification process and the solidification process causes the substrate to become physically or chemically cross-linked, vitrified, or crystallized. As a result of the solidification process, particles are formed. The target pharmaceutical or biological agent within the solution retains proper conformation to ultimately produce a desired effect.

Through sourcing net-primary productivity additive algae-based biomass feedstock, the exclusive use of renewable energy in processing, and the appropriate formulation and processing, a novel algae-derived bio-based plastic is both carbon-negative and provides some performance advantages over existing algae-based film plastics especially with regard to optical clarity. A system may be provided that produces a carbon-negative bioplastic. The production of the bioplastic in a process chamber may be controlled by an electronic controller. The electronic controller may be controlled by a host system, such a server. The electronic controller may be configured to direct production of the bioplastic in the process chamber using hydrocolloid, which is derived from algae.

Provided is a bioink set for printing a construct that is able to carry cells, including a bioink which contains a biodegradable polyurethane and a biopolymer, and a divalent metal ion solution. The biopolymer is gelatin, agar, alginate salts, hyaluronic acid and salts thereof, chitosan, and any combination thereof. Also provided are a method of preparing a construct for carrying cells by three-dimensional printing with the bioink set, and a method of three-dimensional printing of cells by using an ink composition.

The disclosure provides a biodegradable material and its preparation method and application, which solves the problems of a harsh preparation condition of a biodegradable material, a rough surface on a film formed by the prepared biodegradable material, pores existing in a cross section. The biodegradable material of the present disclosure is high in preparation efficiency and simple in preparation process and energy consumption saving without necessary high-temperature and high-pressure conditions. There is no obvious difference between its degradation performance and the degradation performance of the biodegradable material prepared by the conventional high-temperature high-pressure method. The biodegradable material is suitable for preparing a film to be applied to a field of packaging materials. The prepared film may be completely degraded in about 15 days. The prepared film is smoother on surface and more excellent in toughness and malleability compared with the film prepared under conventional high-temperature and high-pressure conditions.
