This disclosure provides generally for antimicrobial compositions and methods of use comprising an anthocyanin, an anthocyanidin or metabolites thereof. Methods for promoting healing of a wound using these compositions are also disclosed. These compositions have broad spectrum antimicrobial activity and are safe for human and animal uses. Further, these compositions are safe for medical uses and industrial uses as antiseptic preparations to reduce or prevent microbial growth, including killing bacterial biofilms.

To perform sterilization using a sterilization member that has a treatment surface that is a surface on which a plurality of protrusions each having a leading end that is thinner than a diameter of a microorganism that is to be killed are provided, a sterilization member on which each protrusion has a height that is greater than or equal to half the diameter of the microorganism that is to be killed is used as the sterilization member, and a fluid that contains the microorganism that is to be killed is caused to strike the treatment surface to kill the microorganism that is to be killed.

A disposable, single-use wipe that can be used deodorize, disinfect, and/or sterilize an object. A wipe includes a flexible membrane or cloth-like element that may apply, distribute, and/or remove a treatment agent to, over, or from a surface of the object. A treatment agent, such as micron-, or nano-sized particles of a disinfectant or sterilant chemical, Ozone, negative ions, Hydroxyl radicals, or alcohol, etc., may be applied to the surface by the wipe or another applicator. An additional treatment agent (e.g., Triclosan, Chlorine dioxide, Hydroxyl radicals, etc.), may be associated with a wipe to enhance biocidal activity. The wipe may be used alone, in combination with a holder, or in combination with an applicator of energized treatment agent. An applicator and/or a holder may be used to energize one or more treatment agent to improve its efficacy.

The present invention provides a surface treatment method that improves antimicrobial activity of copper or a copper alloy and enhances immediate effects of antimicrobial actions on the surface of the copper or the copper alloy. A surface treatment method for copper or a copper alloy according to the present invention comprises preparing a reducing agent solution containing a biological reducing substance, and treating the surface of the copper or the copper alloy with the reducing agent solution. The present invention also provides a surface treatment liquid for sterilizing copper or a copper alloy, in which the surface treatment liquid contains a biological reducing substance. The present invention also provides a sterilization method that comprises bringing copper or a copper alloy treated by the surface treatment method into contact with a surface of an object to sterilize the surface of the object.

A device for automatically disinfecting a portion of a medical implement. The device includes a reservoir chamber having a top external opening, a medical implement protruded through a bottom part of the reservoir chamber with the portion to be disinfected exposed inside the reservoir chamber and below the top external opening, two disinfecting pads, and a resilient device. Each disinfecting pad is connected to the reservoir chamber through a mounting member, which permits displacement of the disinfecting pads relative to the reservoir chamber in substantially opposite directions thereby creating a gap between each pad and the portion to be disinfected. The resilient device biases the disinfecting pads such that when the disinfecting pads are displaced from a rest position, wherein they are contacting the portion to be disinfected, to an engaged position, the disinfecting pads are urged to return toward the portion to be disinfected to contact and disinfect the portion.
