The core can include any of a thermochromic material, a phase-change material, and a judiciously defined auxiliary material that in turn contains organic and/or polymeric material. Derivative products utilizing a plurality of such particles. Methodologies for producing such particles and derivative products.

Disclosed herein is a transportable bio-cement comprising a desiccated microorganism package; where the microorganism package comprises one or more microorganisms; a first binder, where the first binder is produced by the microorganism; and where the microorganism has protected itself by a layer of the first binder; where the transportable bio-cement is devoid of moisture. Disclosed herein too is a method of manufacturing a transportable dry composition comprising blending together a microorganism package; a nutrient; and a liquid; activating the microorganism package to produce a first binder; subjecting the microorganism package to desiccation to form a transportable bio-cement; and blending the transportable bio-cement with an aggregate to form a bio-concrete; where the aggregate comprises a substrate, a second binder, and a liquid.
