Disclosed is an anti-algal agent to inhibit algal growth on articles treated with the anti-algal agent. Initially, a Supramolecular Macrocyclic Inorganic Polymer (SMIP) having multiple voids is derived. The voids are in a crystal structure of the SMIP. The SMIP is derived from a metallic element having a multiple valance. The metallic element may have a differential polarity, a hydrogen bonding ability, and an imbalanced electronic orbital energy disposition. Further, a Technical Grade Active Ingredient (TGAI) may be infused in the voids of the SMIP to obtain an anti-algal agent. The anti-algal agent may act as at least one of a biocides or as a preservative to inhibit algal growth on the articles treated. Furthermore, the anti-algal agent when used for treating on properties of treated articles may avoid deterioration of the article from microbial attacks.

Provided herein are rapid, large-scale screening methods for identifying metal-biocide combinations that are synergistically effective to kill or inhibit the growth of microorganisms. Also provided herein are novel, synergistically antimicrobial metal-biocide combinations and uses of such compositions to curb or slow microbial growth.

A biocide blend can be used in an oil or gas operation. The biocide blend can include a first biocide of a formaldehyde-releasing biocide and a second biocide of a quaternary ammonium compound. The formaldehyde-releasing biocide can release formaldehyde after introduction into a wellbore. The first and second biocide can possess at least one property that is the same. The first biocide and/or the second biocide can maintain biocidal activity for extended periods of time in high salinity wellbore fluids, be thermally stable, and less expensive than other biocides.
