In alternative embodiments, provided are products of manufacture and kits, and methods, for delivering macromolecules, including nucleic acids such as DNA and RNA, including genes and protein-encoding nucleic acids, to the skin, or the dermis or epidermis, and mucosa. In alternative embodiments, provided are products of manufacture and kits, and methods, for detecting macromolecules, including nucleic acids such as DNA and RNA, including genes and protein-encoding nucleic acids, in skin, epidermal or mucosal cells. In alternative embodiments, exemplary products of manufacture are physically flexible nanodelivery devices that are wearable, e.g., they can be worn as patches on the skin or mucosa. In alternative embodiments, nanodelivery devices provided herein are fabricated in a microelectrodemicrofluidicnanochannel configuration which can precisely deliver cargo into the touched cells upon localized and safe-voltage electroporation. The on-skin electroporation can be wirelessly powered and controlled via on-chip near field communication (NFC) module. An accessory skin sensor can be simultaneously implemented on the same chip for skin impedance detection at the same time.

The present disclosure relates to a decoration member comprising a color developing layer comprising a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on one surface of the color developing layer, wherein the light absorbing layer comprises a molybdenum-titanium oxide (Mo.sub.aTi.sub.bO.sub.x).

Fabrics made for apparel, tents, sleeping bags and the like, in various composites, constructed such that a combination of substrate layers and insulation layers is configured to provide improved thermal insulation. The fabric composites are constructed to form a radiant barrier against heat loss via radiation and via conduction from a body.

Provided is a joint manufacturing method including: a step A of preparing a laminate in which two objects to be joined are temporarily adhered with a heat-joining sheet including a pre-sintering layer interposed between the two objects to be joined; a step B of increasing a temperature of the laminate from a temperature equal to or lower than a first temperature defined below to a second temperature; and a step C of holding the temperature of the laminate in a predetermined range after the step B, in which the laminate is pressurized during at least a part of the step B and at least a part of the step C. The first temperature is a temperature at which an organic component contained in the pre-sintering layer is decreased by 10% by weight when the pre-sintering layer is subjected to thermogravimetric measurement.

A member includes a base material and an electroless plating layer. The base material includes an elastic section that includes a sulfur-containing elastic body. The electroless plating layer is provided on the elastic section of the base material. The base material includes the elastic section, and the electroless plating layer is positioned on one surface of the elastic section. The elastic section has a portion that is elastically deformable together with the electroless plating layer.
