Claim 5:
6. The method of claim 4 wherein developing biological trace evidence additionally includes:
immersing the sample in the biological fluorescent development reagent or spraying the biological fluorescent development reagent on the sample at the at least one identified location;
drying the sample in an environment having a relative humidity of less than 40% at a temperature of 50° C.-120° C.;
irradiating the dried sample with a laser having a wavelength of 532 nm and a full width at half-maximum of less than 1 nm;
controlling a surface of the sample with an illuminance of over 300,000 lux; and
using a cut-off filter under 540 nm to develop the biological trace evidence on the sample.
